American Sports Network (ASN) was the sports division of the U.S. television station owner Sinclair Broadcast Group through its Sinclair Networks subsidiary. Formed in July 2014, ASN produces broadcasts of sporting events that are aired primarily across stations owned by Sinclair (in particular, The CW and MyNetworkTV stations owned and/or operated by the company, or, in some markets, on a digital subchannel of a Sinclair station), and syndicated to non-Sinclair stations and regional sports networks.
ASN primarily dealt in college sports from NCAA Division I conferences, including live football and basketball games from the Atlantic 10 Conference, Big South Conference, Colonial Athletic Association, Conference USA, Horizon League, Ivy League, Mid-American Conference, Ohio Valley Conference, Patriot League, Southern Conference, Southland Conference, and Western Athletic Conference, as well as a limited number of professional sports events. In 2015, ASN acquired regional rights to Real Salt Lake and D.C. United of Major League Soccer, with games airing on Sinclair stations in the teams' market area, as well as television rights to the newly established Arizona Bowl.
In 2017, Sinclair announced that it would fold ASN into a new joint venture with Silver Chalice known as Stadium, which would combine ASN's broadcast distribution platforms with content from Silver Chalice's digital outlets 120 Sports and Campus Insiders. ASN formally dissolved on August 23, 2017, although ASN programming continued on-air until September 6, when the network formally transitioned on-air to Stadium.
Sinclair Broadcast Group formally announced the launch of the American Sports Network on July 17, 2014; the service was led by Doron Gorshein, who joined the company in January 2014 in the role of chief operating officer of Sinclair Networks. ASN carries live broadcasts of mainly collegiate sporting events, along with ancillary programming focusing on colleges, their students and student-athletes. ASN's content would air primarily on Sinclair-owned-or-operated affiliates of The CW and MyNetworkTV or on secondary digital subchannels of other stations run by the company (some of which had carried content from competing syndicated sports distributors ESPN Regional Television and Raycom Sports until ASN's launch), the latter especially the case for its stations that have primary affiliations with one of the Big Four networks (ABC, NBC, CBS and Fox) which would not pre-empt the higher-tier sports coverage provided by their network partners. Sinclair opened ASN up for distribution by other broadcast outlets interested in carrying the service's content, and announced plans to expand ASN onto digital platforms.
ASN planned to initially broadcast college football, men's and women's college basketball, women's college soccer, and college baseball events, beginning with the 2014 NCAA Division I FBS and FCS football seasons. Prior to the service's formal launch, Sinclair reached broadcast rights agreements with five NCAA Division I conferences, including Conference USA, the Colonial Athletic Association, Big South Conference, Southern Conference, and the Patriot League.
ASN's first broadcasts took place on August 30, 2014, featuring two football games involving Conference USA teams (Old Dominion University vs. Hampton University and Florida International University hosting Bethune-Cookman University).
In September 2014, Sinclair reached a two-year deal with the International Motor Sports Association to syndicate broadcasts of the Porsche GT3 Cup Challenge series through ASN beginning that year, with a renewal option that could be exercised in 2016. Its first race broadcast on September 13, 2014 was shown on Sinclair stations in at least 36 markets, marking the first non-college sporting event to be syndicated by ASN.
On September 29, 2014, Sinclair announced a multi-year deal with the Western Athletic Conference to broadcast its games through ASN – marking the sixth conference to partner with the service. Sinclair also announced that it had reached syndication deals with stations in 67 markets where the company does not have a station in its portfolio to carry ASN's programming, expanding its total potential audience to 83 million viewers.
On October 16, 2014, Jonathan B. LeCrone announced the Horizon League had entered into a deal with the American Sports Network to broadcast select games; subsequently on November 10, ASN entered into a broadcast contract with the Ohio Valley Conference.
On December 2, 2014, ASN entered into the collegiate hockey field through an agreement that gave it the rights to air six Penn State Nittany Lions home games. ASN later added two other men's ice hockey contests from the Big Ten Conference, featuring the Wisconsin Badgers and Ohio State Buckeyes.
On January 23, 2015, Sinclair announced that it had acquired regional television rights to Real Salt Lake of Major League Soccer beginning in the 2015 season, with ASN handling production of the telecasts. KMYU and KUTV will air the games locally, and they will be syndicated to Sinclair stations in Las Vegas and Reno, Nevada as well as in Boise, Idaho. Stations in Arizona and New Mexico would also be able to bid for the local rights to telecast the matches in their markets.
On May 19, 2015, ASN announced that it had reached an agreement with Minor League Baseball (MiLB) to televise a weekly game during the 2015 season. ASN was scheduled to air a weekly game live from different individual leagues on Sunday nights, and would also air the all-star games for the Florida State League and the Midwest League.
On June 24, 2015 the Southland Conference announced that ASN would televise select matches from their conference beginning with the 2015 fall football season. The ASN package would replace the Southland Conference TV Network syndication package.
In September 2015, ASN reached a deal with the Mid-American Conference, sub-licensed through ESPN, to broadcast selected games. In the 2015–16 academic season, ASN will broadcast 10 football games, 10 men's basketball games, and 5 women's basketball games. ASN also reached deals with the NCAA Division I ice hockey conferences, including the Big Ten, ECAC Hockey, Hockey East, National Collegiate Hockey Conference, and the Western Collegiate Hockey Association, to broadcast games as part of a Friday night package.
On December 18, 2015, D.C. United of Major League Soccer announced that Sinclair had acquired rights to the team. ASN-produced coverage is aired by News Channel 8 and WJLA-TV. Matches are also syndicated to digital subchannels of WUTB Baltimore, WRLH Richmond, WTVZ Norfolk, and WSET Roanoke.
On January 8, 2016, Sinclair announced a dedicated American Sports Network channel, offered as an affiliation for digital subchannels of stations in Baltimore, Charleston, Cincinnati, Columbus, Greensboro, Myrtle Beach, Nashville, Pittsburgh, Portland, and Raleigh-Durham. The service launched on January 11, 2016.
In March 2017, unconfirmed reports speculated that Sinclair was planning to shutter ASN and give its remaining sports rights to Campus Insiders. The Charleston Gazette-Mail, however, citing ASN employees, reported that the rumors of a complete shuttering were false, but that the division was planning to re-locate its headquarters, restructure its operations, and achieve "stronger, more diversified distribution." The original rumors were based upon reports of layoffs from ASN's current headquarters in West Palm Beach, connected to the planned re-location.
On April 13, 2017, Sinclair officially announced that ASN would be re-launched later in the year as part of a joint venture with Silver Chalice (owner of Campus Insiders) and its online sports video service 120 Sports. The new operation will be operated as linear and digital offerings; the linear service would utilize the syndication and broadcast network built out for ASN, while the digital platform will stream full-time online and through Twitter. 120 Sports will provide original studio and long-form programming to the venture. On May 1, 2017, it was announced that the new joint venture would be known as Stadium. On June 1, 2017, it was reported that Stadium would officially launch around late-July 2017. After a soft launch in July 2017, the service officially launched on August 24, with ASN's over-the-air network formally joining Stadium on September 6.
