The future of New York’s longtime community-supported radio station WBAI is up in the air. On Monday, the Pacifica Foundation abruptly laid off WBAI’s staff and ended local programming. But then, on Monday night, a New York state judge issued a temporary restraining order enjoining Pacifica from shutting down the station. A court hearing is set for October 18. Local programming is expected to resume today. WBAI is one of five stations in the Pacifica Radio network, which was founded in 1949 by the peace activist Lew Hill.
