Network

Network is a movie starring Faye Dunaway, William Holden, and Peter Finch. A television network cynically exploits a deranged former anchor's ravings and revelations about the news media for its own profit.
When veteran anchorman Howard Beale is forced to retire his 25-year post because of his age, he announces to viewers that he will kill himself during his farewell broadcast. Network executives rethink their decision when his fanatical tirade results in a spike in ratings.
