National Public Radio (usually shortened to NPR, stylized as npr) is an American privately and publicly funded non-profit membership media organization that serves as a national syndicator to a network of 900 public radio stations in the United States. 
NPR produces and distributes news and cultural programming. Individual public radio stations are not required to broadcast all NPR programs; most broadcast a mix of NPR programs, content from rival providers American Public Media, Public Radio International, Public Radio Exchange and WNYC Studios, and locally produced programs. The organisation's flagship shows are two drive-time news broadcasts, Morning Edition and the afternoon All Things Considered; both are carried by most NPR member stations, and are among the most popular radio programs in the country.   As of October 2017, the drive time programs attract an audience of 14.63 million and 14.6 million respectively. 
NPR manages the Public Radio Satellite System, which distributes NPR programs and other programming from independent producers and networks such as American Public Media and Public Radio International. Its content is also available on-demand online, on mobile networks, and, in many cases, as podcasts.
The organization's legal name is National Public Radio and its trademarked brand is NPR; it is known by both names.  In June 2010, the organization announced that it was "making a conscious effort to consistently refer to ourselves as NPR on-air and online" because NPR is the common name for the organization and the tag line "This ... is NPR" has been used by its radio hosts for many years.  However, National Public Radio remains the legal name of the group, as it has been for more than 45 years. 
National Public Radio replaced the National Educational Radio Network on February 26, 1970, following Congressional passage of the Public Broadcasting Act of 1967. This act was signed into law by 36th President Lyndon B. Johnson, and established the Corporation for Public Broadcasting, which also created the Public Broadcasting Service (PBS) for television in addition to NPR. A CPB organizing committee under John Witherspoon first created a Board of Directors chaired by Bernard Mayes.
NPR aired its first broadcast in April 20, 1971, covering United States Senate hearings on the ongoing Vietnam War in Southeast Asia. A month later, the afternoon drive-time newscast All Things Considered began, on May 3, 1971, first hosted by Robert Conley. NPR was primarily a production and distribution organization until 1977, when it merged with the Association of Public Radio Stations.
NPR suffered an almost fatal setback in 1983 when efforts to expand services created a deficit of nearly US$7 million. After a Congressional investigation and the resignation of NPR's then president, Frank Mankiewicz, the Corporation for Public Broadcasting agreed to lend the network money in order to stave off bankruptcy.  In exchange, NPR agreed to a new arrangement whereby the annual CPB stipend that it had previously received directly would be divided among local stations instead; in turn, those stations would support NPR productions on a subscription basis. NPR also agreed to turn its satellite service into a cooperative venture (the Public Radio Satellite System), making it possible for non-NPR shows to get national distribution. It took NPR approximately three years to pay off the debt. 
Delano Lewis, the president of C&P Telephone, left that position to become NPR's CEO and president in January 1994.  Lewis resigned in August 1998.   In November 1998, NPR's board of directors hired Kevin Klose, the director of the International Broadcasting Bureau, as its president and chief executive officer. 
|“||September 11th made it apparent in a very urgent way that we need another facility that could keep NPR going if something devastating happens in Washington.||”|
|— Jay Kernis, NPR's senior VP for programming |
NPR spent nearly $13 million to acquire and equip a West Coast 25,000-square-foot (2,300 m 2) production facility, NPR West, which opened in Culver City, Los Angeles County, California, in November 2002. With room for up to 90 employees, it was established to expand its production capabilities, improve its coverage of the western United States, and create a backup production facility capable of keeping NPR on the air in the event of a catastrophe in Washington, D.C. 
In November 2003, NPR received US$235 million from the estate of the late Joan B. Kroc, the widow of Ray Kroc, founder of McDonald's Corporation. This was the largest monetary gift ever to a cultural institution.  
In 2004 NPR's budget increased by over 50% to US$153 million due to the Kroc gift. US$34 million of the money was deposited in its endowment.  The endowment fund before the gift totaled $35 million. NPR will use the interest from the bequest to expand its news staff and reduce some member stations' fees.  The 2005 budget was about US$120 million.
In August 2005, NPR entered podcasting with a directory of over 170 programs created by NPR and member stations. By November of that year, users downloaded NPR and other public radio podcasts 5 million times. Ten years later, by March 2015, users downloaded podcasts produced only by NPR 94 million times,  and NPR podcasts like Fresh Air and TED Radio Hour routinely made the iTunes Top Podcasts list. 
Ken Stern became chief executive in September 2006, reportedly as the "hand-picked successor" of CEO Kevin Klose, who gave up the job but remained as NPR's president; Stern had worked with Klose at Radio Free Europe. 
On December 10, 2008, NPR announced that it would reduce its workforce by 7% and cancel the news programs Day to Day and News & Notes.  The organization indicated this was in response to a rapid drop in corporate underwriting in the wake of the economic crisis of 2008. 
In the fall of 2008, NPR programming reached a record 27.5 million people weekly, according to Arbitron ratings figures. NPR stations reach 32.7 million listeners overall. 
In March 2008, the NPR Board announced that Stern would be stepping down from his role as Chief Executive Officer, following conflict with NPR's Board of Directors "over the direction of the organization" (including issues NPR's member station managers had had with NPR's expansion into new media "at the expense of serving" the stations that financially support NPR). 
As of 2009, corporate sponsorship made up 26% of the NPR budget. 
In October 2010, NPR accepted a $1.8 million grant from the Open Society Institute. The grant is meant to begin a project called Impact of Government that was intended to add at least 100 journalists at NPR member radio stations in all 50 states by 2013.  The OSI has made previous donations, but does not take on air credit for its gifts. 
In April 2013, NPR moved from its home of 19 years (635 Massachusetts Avenue NW) to new offices and production facilities at 1111 North Capitol Street NE in a building adapted from the former C&P Telephone Warehouse and Repair Facility.  The new headquarters—at the corner of North Capitol Street NE and L Street NW—is in the burgeoning NoMa neighborhood of Washington.  The first show scheduled to be broadcast from the new studios was Weekend Edition Saturday.  Morning Edition was the last show to move to the new location.  In June 2013 NPR canceled the weekday call-in show Talk of the Nation. 
In September 2013, certain of NPR's 840 full- and part-time employees were offered a voluntary buyout plan, with the goal of reducing staff by 10 percent and returning NPR to a balanced budget by the 2015 fiscal year. 
NPR is a membership organization. Member stations are required to be non-commercial or non-commercial educational radio stations; have at least five full-time professional employees; operate for at least 18 hours per day; and not be designed solely to further a religious broadcasting philosophy or be used for classroom distance learning programming. Each member station receives one vote at the annual NPR board meetings—exercised by its designated Authorized Station Representative ("A-Rep").
To oversee the day-to-day operations and prepare its budget, members elect a Board of Directors. This board is composed of ten A-Reps, five members of the general public, and the chair of the NPR Foundation. Terms are for three years and are staggered such that some stand for election every year. 
As of March 2015, the Board of Directors of NPR included the following members: 
- NPR Member Station Managers
- Mike Crane, Director, Wisconsin Public Radio
- Betsy Gardella, President and CEO, New Hampshire Public Radio
- Kit Jensen, Chief Operating Officer WVIZ/PBS & 90.3 WCPN ideastream, Chair of the Board
- Roger LaMay, General Manager, WXPN
- Caryn Mathes, President and General Manager, KUOW
- Greg Petrowich, Executive Director, WSIU Public Broadcasting
- Florence Rogers, President and General Manager, Nevada Public Radio
- Mike Savage, General Manager, WBAA
- Kerry Swanson, Station Manager, Northwest Public Radio
- Connie Walker, General Manager, WUNC

- Public Members of the Board
- Fabiola Arredondo, Managing Partner, Siempre Holdings
- Chris Boskin, Media Company Consultant
- Patricia Diaz Dennis, Senior Vice President and Assistant General Counsel, Retired, AT&T
- Paul G. Haaga, Jr., Chairman of the Board, Retired, Capital Research and Management Company
- John S. Wotowicz, Managing Partner of Concentric Capital, Vice Chair of the Board
The original purposes of NPR, as ratified by the Board of Directors, are the following:
- Provide an identifiable daily product which is consistent and reflects the highest standards of broadcast journalism.
- Provide extended coverage of public events, issues and ideas, and to acquire and produce special public affairs programs.
- Acquire and produce cultural programs which can be scheduled individually by stations.
- Provide access to the intellectual and cultural resources of cities, universities and rural districts through a system of cooperative program development with member public radio stations.
- Develop and distribute programs for specific groups (adult education, instruction, modular units for local productions) which may meet needs of individual regions or groups, but may not have general national relevance.
- Establish liaison with foreign broadcasters for a program exchange service.
- Produce materials specifically intended to develop the art and technical potential of radio 
- NPR Ombudsman/Public Editor
The Ombudsman/Public Editor responds to significant listener queries, comments and criticisms.  The position reports to the President and CEO Jarl Mohn.  Elizabeth Jensen was appointed to a three-year term in January 2015. 
In 2010, NPR revenues totaled $180 million, with the bulk of revenues coming from programming fees, grants from foundations or business entities, contributions and sponsorships.  According to the 2009 financial statement, about 50% of NPR revenues come from the fees it charges member stations for programming and distribution charges.  Typically, NPR member stations receive funds through on-air pledge drives, corporate underwriting, state and local governments, educational institutions, and the federally funded Corporation for Public Broadcasting (CPB). In 2009, member stations derived 6% of their revenue from federal, state and local government funding, 10% of their revenue from CPB grants, and 14% of their revenue from universities.   While NPR does not receive any direct federal funding, it does receive a small number of competitive grants from CPB and federal agencies like the Department of Education and the Department of Commerce. This funding amounts to approximately 2% of NPR's overall revenues. 
During the 1970s and early 1980s, the majority of NPR funding came from the federal government. Steps were taken during the 1980s to completely wean NPR from government support, but forced the network to make immediate changes. According to CPB, in 2009 11.3% of the aggregate revenues of all public radio broadcasting stations were funded from federal sources, principally through CPB;  in 2012 10.9% of the revenues for Public Radio came from federal sources. 
In 2011, NPR announced the roll-out of their own online advertising network, which allows member stations to run geographically targeted advertisement spots from national sponsors that may otherwise be unavailable to their local area, opening additional revenue streams to the broadcaster. 
In 2014, NPR CEO Jarl Mohn said the network would begin to increase revenue by having brands NPR views as more relevant to the audience underwrite NPR programs and requesting higher rates from them. 
Underwriting spots vs. commercials
In contrast with commercial broadcasting, NPR's radio broadcasts do not carry traditional commercials, but has advertising in the form of brief statements from major sponsors which may include corporate slogans, descriptions of products and services, contact information such as website addresses and telephone numbers.  These statements are called underwriting spots and, unlike commercials, are governed by specific FCC restrictions in addition to truth in advertising laws; they cannot advocate a product or "promote the goods and services" of for-profit entities.  These restrictions apply only to radio broadcasts and not NPR's other digital platforms. When questioned on the subject of how corporate underwriting revenues and foundation grants were holding up during the recession, in a speech broadcast on C-SPAN before the National Press Club on March 2, 2009, then President and CEO Vivian Schiller stated: "underwriting is down, it's down for everybody; this is the area that is most down for us, in sponsorship, underwriting, advertising, call it whatever you want; just like it is for all of media."  Hosts of the NPR program Planet Money stated the audience is indeed a product being sold to advertisers in the same way as commercial stations, saying: "they are not advertisers exactly but, they have a lot of the same characteristics; let's just say that." 
A Harris telephone survey conducted in 2005 found that NPR was the most trusted news source in the United States. 
According to 2009, NPR statistics, about 20.9 million listeners tune into NPR each week.  According to 2015 figures, 87% of the NPR terrestrial public radio audience and 67% of the NPR podcast audience is white.  According to the 2012 Pew Research Center 2012 News Consumption Survey, NPR listeners tend to be highly educated, with 54% of regular listeners being college graduates and 21% having some college.  NPR's audience is almost exactly average in terms of the sex of listeners (49% male, 51% female).  NPR listeners have higher incomes than average (the 2012 Pew study showed that 43% earn over $75,000, 27% earn between $30,000 and $75,000).  The Pew survey found that the NPR audience tends Democratic (17% Republican, 37% independent, 43% Democratic) and liberal (21% conservative, 39% moderate, 36% liberal). 
NPR stations generally do not subscribe to the Arbitron rating service and are not included in published ratings and rankings such as Radio & Records. However, NPR station listenership is measured by Arbitron in both Diary and PPM (people meter) markets. NPR stations are frequently not included in "summary level" diary data used by most advertising agencies for media planning. Data on NPR listening can be accessed using "respondent level" diary data. Additionally, all radio stations (public and commercial) are treated equally within the PPM data sets making NPR station listenership data much more widely available to the media planning community. According to Arbitron's National Broadcast Audience Estimate report for September 29, 2011,  NPR's signature morning news program, Morning Edition, is the network's most popular program, drawing 12.9 million listeners a week, with its afternoon newsmagazine, All Things Considered, a close second, with 12.2 million listeners a week. Arbitron data is also provided by Radio Research Consortium, a non-profit corporation which subscribes to the Arbitron service and distributes the data to NPR and other non-commercial stations and on its website. 
NPR's history in digital media includes the work of an independent, for-profit company called Public Interactive, which was founded in 1999  and acquired by PRI in June 2004, when it became a non-profit company.  By July 2008, Public Interactive had "170 subscribers who collectively operate 325 public radio and television stations" and clients such as Car Talk, The World, and The Tavis Smiley Show; by the end of that month, NPR acquired Public Interactive from PRI  In March 2011, NPR revealed a restructuring proposal in which Boston-based Public Interactive would become NPR Digital Services, separate from the Washington D.C.-based NPR Digital Media, which focuses on NPR-branded services.  NPR Digital Services would continue offering its services to public TV stations. 
NPR has been dubbed as "leveraging the Twitter generation"  because of its adaptation of the popular microblogging service as one of its primary vehicles of information. Of NPR's Twitter followers, the majority (67%) still do listen to NPR on the radio. In a survey of more than 10,000 respondents, NPR found that its Twitter followers are younger, more connected to the social web, and more likely to access content through digital platforms such as its Peabody Award -winning website npr.org, as well as podcasts, mobile apps and more.  NPR has more than one Twitter account including @NPR;  its survey found that most respondents followed between two and five NPR accounts, including topical account, show-specific accounts and on-air staff accounts.  In addition, NPR's Facebook page has been at the forefront of the company foray into social media. Started by college student and fan Geoff Campbell  in 2008, the page was quickly taken over by the organization,  and over the last two years has grown to nearly 4 million fans and is a popular example of the company's new focus on a younger audience. 
In July 2014, NPR launched NPR One, an app for iOS and Android smartphones and other mobile devices, which aimed to make it easier for listeners to stream local NPR stations live, and listen to NPR podcasts by autoplaying content and permitting easy navigation.  Since launch NPR has made the service available on additional channels: Windows mobile devices, web browsers, Chromecast, Apple Car Play, Apple Watch, Android Auto, Android Wear, Samsung Gear S2 and S3, Amazon Fire TV, and Amazon Alexa -enabled devices.

Many shows produced or distributed by Public Radio International—such as Living on Earth —are broadcast on public radio stations, but are not affiliated with NPR. PRI and NPR are separate production and distribution organizations with distinct missions, and each competes with the other for programming slots on public radio stations.
Public Radio Exchange also offers a national distribution network where a significant number of public radio stations go to acquire programs from independent producers. PRX provides a catalog of thousands of radio pieces available on-demand as broadcast quality audio files and available for streaming on the PRX.org website.
Most public radio stations are NPR member stations and affiliate stations of PRI, APM, and PRX at the same time. The organizations have different governance structures and missions and relationships with stations. Other popular shows, like A Prairie Home Companion and Marketplace, are produced by American Public Media, the national programming unit of Minnesota Public Radio. These programs were distributed by Public Radio International prior to APM's founding. Democracy Now!, the flagship news program of the Pacifica Radio network, provides a feed to NPR stations, and other Pacifica programs can occasionally be heard on these stations as well.
Over the course of NPR's history, controversies have arisen over several incidents and topics.
Allegations of ideological bias
NPR has been accused of displaying both liberal bias, as alleged in work such as a UCLA and University of Missouri study of Morning Edition, and conservative bias, including criticism of alleged reliance on conservative think-tanks.  NPR has also been accused of bias related to specific topics, including support of the 2003 Invasion of Iraq and coverage of Israel. The NPR ombudsman has described how NPR's coverage of the Israel-Palestinian conflict has been simultaneously criticized as biased by both sides.  UT Austin journalism professor and author Robert Jensen has criticized NPR as taking a pro-war stance during coverage of Iraq war protests. 
In 2002 and 2003, surveys and follow-up focus groups conducted by the Tarrance Group and Lake Snell Perry & Associates have indicated that, "The majority of the U.S. adult population does not believe that the news and information programming on public broadcasting is biased. The plurality of Americans indicate that there is no apparent bias one way or the other, while approximately two-in-ten detect a liberal bias and approximately one-in-ten detect a conservative bias." 
In a controversial act, NPR banned in 2009 the use of the word "torture" in the context of the Bush administration's use of enhanced interrogation techniques.  NPR's Ombudswoman Alicia Shepard's defense of the policy was that "calling waterboarding torture is tantamount to taking sides."  But Berkeley Professor of Linguistics, Geoffrey Nunberg pointed out that virtually all media around the world, other than what he called the "spineless U.S. media", call these techniques torture.   In an article which criticized NPR and other U.S. media for their use of euphemisms for torture, Glenn Greenwald discussed what he called the enabling "corruption of American journalism":
This active media complicity in concealing that our Government created a systematic torture regime, by refusing ever to say so, is one of the principal reasons it was allowed to happen for so long. The steadfast, ongoing refusal of our leading media institutions to refer to what the Bush administration did as "torture" – even in the face of more than 100 detainee deaths; the use of that term by a leading Bush official to describe what was done at Guantanamo; and the fact that media outlets frequently use the word "torture" to describe exactly the same methods when used by other countries – reveals much about how the modern journalist thinks. 
In October 2017, sexual harassment charges were leveled against Michael Oreskes, senior vice president of news and editorial director since 2015. Some of the accusations dated back to when he was Washington, DC bureau chief for The New York Times during the 1990s, while others involved his conduct at NPR.  After a report on the Times accusations was published in The Washington Post, NPR put Oreskes on administrative leave, and the following day his resignation was requested.    CNN's Brian Stelter reported that NPR staffers were dissatisfied with the handling of Oreskes, were demanding an external investigation, and that Oreskes poisoned the newsroom atmosphere by abusing his position to meet young women. 
Live from Death Rowcommentaries
In 1994, NPR arranged to air, on All Things Considered, a series of three-minute commentaries by Mumia Abu-Jamal, a journalist convicted in a controversial trial of murdering a Philadelphia Police officer. They cancelled airing them after the Fraternal Order of Police and members of the U.S. Congress objected.
Juan Williams comments
Ronald Schiller comments
In March 2011, conservative political activist and provocateur James O'Keefe sent partners Simon Templar (a pen name) and Shaughn Adeleye  to secretly record their discussion with Ronald Schiller, NPR's outgoing senior vice president for fundraising, and an associate, in which Schiller made remarks viewed as disparaging of "the current Republican party, especially the Tea Party ", and controversial comments regarding Palestine and funding for NPR. NPR disavowed Schiller's comments. CEO Vivian Schiller, who is not related to Ronald, later resigned over the fallout from the comments and the previous firing of Juan Williams. 
July 4th Tweets of the Declaration of Independence
Starting from July 4, 1988, NPR has broadcast an annual reading of the United States Declaration of Independence over the radio.  In addition, it has recently begun using Twitter as a medium for reading the document as well. On July 4, 2017, the yearly tweets were met with considerable opposition, some online supporters of Donald Trump mistakenly believing the words of the declaration referring to George III of the United Kingdom to be directed towards the president. The tweets have been accused of being propagandistic,  condoning of violence,  and calling of revolution.   Many of the responses to NPR's tweets have since been retracted.
