This just in: Layoffs are about to hit one of public broadcasting’s signature shows. The New York Times reports that PBS NewsHour, the nightly newscast launched in 1975, is closing its San Francisco and Denver offices — its only outlets outside the D.C. area — and pink-slipping most of the staffers there. It will be the show’s first major round of layoffs since the mid-‘90s. Producer MacNeil/Lehrer Prods also will cut some jobs at NewsHour’s Arlington, Va., headquarters and make cutbacks by not filling vacant positions and streamlining. The reason? A decrease in corporate sponsorship. A NewsHour spokeswoman told the Times that the reorganization, which will take place over several months starting in July, would help balance the budget.
