In its early days, KQED was “boiling with ideas,” says an old timer in the San Francisco Chronicle‘s series marking the station’s 50th anniversary this week. [See also David Stewart’s retrospective from Current.] The first public TV station, KUHT, celebrated its 50th last year. Also turning 50 this year are stations in East Lansing, Mich.; Pittsburgh; Madison, Wis.; Cincinnati; St. Louis; Lincoln, Neb.; and Seattle.
