The semiannual events, attended by hundreds of critics and reporters, are key opportunities for the networks to expose new shows to broad audiences.

After the strike began Nov. 5, TCA officials had hoped to deliver a smaller tour devoted to networks' altered midseason schedules.

Those lineups now will be composed of reality shows and repeats, with a smattering of scripted dramas mostly completed before the work stoppage. But the networks, worried that reporters would pelt executives with questions about the strike, cooled to the idea of a stripped-down tour, according to officials interviewed in recent weeks. The networks also believed that actors and writers would not show up for promotional activities during the strike.
