on Channel One Russia follows a similar schedule to this one, with Vremya, Novosti, and the all-Russian and regional news updates. The majority of Russians rely on Vremya as a trusted news source. Between 1980 to 1984, and since 1986, Vremya has used the theme song from Time, Forward! as its signature tune and opening sequence. In a two-week test that lasted from 12 to 23 February 1990, more than 100 PBS member stations across the United States broadcast Vremya. The test was coordinated by WGBH-TV. The test was then extended for another two weeks, but was not carried by all of the same stations. Coverage during the last days of the USSR After the introduction of the glasnost and perestroika, Vremya loosened its fidelity to the party line and began presenting fair reports about the events transforming Eastern Europe at the time. On 15 March 1989 150 million Soviet citizens watched as the station aired an 85-page speech by Gorbachev to a plenum of the CPSU Central Committee criticizing the poor state of agriculture and setting out the case for reforms, the highlights of that address being featured on that day's telecast. In the 1980s, 86% of Soviet adults relied on television coverage as their primary source of news. Yet Vremya was seen as "a joke" by many Soviet citizens due to its poor coverage of news events. The coverage of the Chernobyl nuclear disaster, for example, was often relegated to lesser news items during the ongoing coverage of the disaster; in contrast, western news media such as CBS Evening News led with the story for six consecutive weekdays. Following the evacuation of the nuclear workers' closed city of Pripyat, Vremya issued the following brief announcement: In 1987 the program logo appeared for the first time in its studio. 1988 saw a big change for the newscast as its studios featured picture backdrops for the first time, and debuted a new logo, with a styled letter В in a box (this was the year of its 20th anniversary). On 19 August 1991 it showed pictures of the impending coup d'etat in Moscow for the first time, albeit in the new styled studios which opened in 1990. Vremya covered highlights of the March 1989 elections for the Congress of People's Deputies of the Soviet Union and the sessions of the Congress in Moscow, making interviews with its leadership and deputies.
