The San Bernardino Sun is a paid daily newspaper in San Bernardino County, along with a heavy penetration into neighboring Riverside County. The SB Sun serves most of the Inland Empire in Southern California. The geographic circulation area of the newspaper spans from the border of Los Angeles/Orange Counties to the west, east to the Arizona State line, north to the Imperial County line, and south to the Riverside City line. The SB Sun's local competitors are The Press-Enterprise in Riverside. It publishes the annual PrepXtra high school football magazine with capsules and schedules for all schools located in the Pomona Valley and San Bernardino County
The San Bernardino Sun began press in 1894. Times Mirror, the owner of the Los Angeles Times, bought the paper in 1964, but was ordered to sell it due to antitrust concerns. Gannett purchased the paper in 1968. MediaNews Group took control of the paper from Gannett in 1999. This made the Sun sister newspaper to, ironically, the Times' rival, the Los Angeles Daily News. The San Bernardino Sun is a member of Southern California News Group.
