Moscow television is to introduce breakfast and late-night news and entertainment shows as part of an overall drive for more openness in the Soviet media, Leonid Kravchenko, deputy chief of the State Committee for Television and Radio, told a Moscow news conference on Monday. Soviet television had for years been “too conservative, pompous and dull,” Kravchenko said. The new breakfast show, from 7 to 8.30 a.m., would replace the repetition of the previous night’s single news program, which for several years has occupied the main spot in morning television. The new show would include fresh news, musical interludes, a press review, weather forecasts and interviews, he said.
