BBC One is attempting to revive Saturday night variety by bringing in big name stars including Johnny Vaughan and Bruce Forsyth.
Bruce Forsyth will host Strictly Come Dancing
Forsyth is to host Strictly Come Dancing, which will pair celebrities with professional ballroom dancers.
And Vaughan will team up with his former Big Breakfast partner Denise Van Outen for a light entertainment show.
Saturday night TV has struggled to attract the big ratings of 1990s shows like Noel's House Party and Blind Date.
BBC One controller Lorraine Heggessey said: "We're trying to move away from that `sameyness' on Saturday night to bring more variety."
"Don't expect every one necessarily to secure the bull's-eye
on its first outing.
"It's really difficult to get entertainment right. We're trying to grow the
next generation of shows. The only way we're going to do that is by a process of trial and error," she added.

Graham Norton will also be joining the station after signing an exclusive deal with the BBC, leaving behind his Channel 4 chat show.
Bafta-winner Bill Nighy is to star in a drama based on Anthony Trollope's novel He Knew He Was Right as part of BBC One's spring/summer season.
The actor, who starred in Love Actually, will be joined by Anna Massey in the story of a disastrous marriage.
Among other drama in the schedule is a big-budget film about The Tamworth Two, a pair of pigs who went on the run from an abattoir sparking a media frenzy, which mixes computer generated graphics with live action.
The drama May 33rd explores the consequences of rituals and satanic abuse as seen through the eyes of a young woman suffering from dissociative identity disorder, previously known as multiple personality disorder.
To mark the 60th anniversary of D-Day on 6 June, BBC One will be staging a drama based on the events surrounding the planning and execution of the invasion of Normandy, as well as telling the stories of the civilians involved.
Bill Nighy's career was boosted by Love Actually
Destination D-Day: Raw Recruits will take 19 young men and put them through the preparations and training exercises their grandfathers might have experienced, accompanied by veterans.
Factual programmes include a series entitled the Stress Test, which follows participants in their everyday life to see how much stress affects their lives.
It will also be a summer of sport as both the Athens Olympics and football's Euro 2004 take place, while Match of the Day returns to the BBC in August showing Premiership highlights.
