Television producer Steven Bochco. With shows like "Hill Street Blues," "L.A.Law," and this season's "NYPD Blue," Bochco can claim credit for a whole TV genre: intensely realistic dramas that use an ensemble cast and multiple, interweaving plots that quickly cut back and forth. TV critics allude to the "Bochco-ization of network TV," as more and more programs use the Bochco trademarks of large casts, gallows humor and allusions to unconventional sex. Bocho remains an innovative, albeit controversial, force in television. His latest series "NYPD Blue" has been rejected by a sizable number of ABC affiliates for vulgarity and nudity. The ratings and critics,though, assert that this is television at its finest. (Rebroadcast of 09/05/1989)
