Because I'm bored, according to wayback TV listings for a Saturday night 25 years ago:
BBC1: MacGyver, Morris Minor's Marvelous Motors, Opportunity Knocks, Columbo, News and Weather, Midnight Caller, The Odd Couple
BBC2: News View, The Session, Far East, Bonded, Cricket
ITV: The A Team, Catchphrase, Moonraker, ITN News, Aspel and Company, Smith and Jones, Darts
Channel4: Brookside, Right to Reply, Glorious Colour, News Summary, Hollywood, Game Set And Match, Allegro Pinchas Zuckerman Here To Make Music, Channel 4 Racing International.
It appears nothing has changed. It's still shit.
