NEW YORK (AP) — PBS was looking forward to a relatively free lane to offer fresh television to viewers downtrodden by the Hollywood strikes this fall, but that advantage may only last a couple of months now. A tentative deal reached late Sunday in the crippling TV writers strike, with hopes that actors would soon follow suit, has given rise to hopes that new episodes of favorite scripted shows might return sometime this winter. With commercial networks largely bereft of fresh material beyond reality shows, sports and game shows, PBS has a fall schedule of new programming, including a heavy dose of nonfiction, led by Ken Burns' look at “The American Buffalo.” “I have to believe that people are looking for new stuff,” said Paula Kerger, CEO of the Public Broadcasting Service.
