WGBH is a member station of National Public Radio (NPR) and affiliate of Public Radio Exchange (PRX) and American Public Media (APM). The license-holder is WGBH Educational Foundation, which also owns company flagship WGBH-TV and WGBX-TV, along with WGBY-TV in Springfield.The station, dubbed Boston Public Radio in 2009, renamed Boston's Local NPR, broadcasts a news-and-information format during the daytime (including NPR News programs and PRX's The World, which is a co-production of WGBH and PRX, and formerly the BBC World Service), and jazz music during the nighttime.Prior to December 1, 2009, the station had a mixed news and entertainment format, featuring local jazz and blues programs, with the station tagline being ‘’Boston’s NPR Arts & Culture Station’’, to differentiate it from all news WBUR-FM, also located in Boston and known at the time as "Boston's NPR News Station". Following the rebranding, much of the station's culture-related programming was dropped in favor of nationally syndicated NPR, PRI, and APM programs.

Great Blue Hill has an elevation of 635 feet (193 m), is located within the Blue Hills Reservation, and is the highest natural point in the Boston area. Mai Cramer, longtime host of the program Blues After Hours, jokingly maintained that the station's call sign stands for: "We Got Blues Here!"According to Nielsen data aggregated by Ken Mills, a Minneapolis broadcast consultant, as of June 2017 the number of WGBH's listeners has nearly doubled since 2012, increasing from 235,200 to 445,200.
