After a year, the series moved to television and Channel 4. Clive continued to host, with John
initially appearing in every episode, and Richard Vranch providing music. The competitive
format was dropped but mysterious "points" were still awarded and a seemingly random winner selected.
Common performers on the show included Greg Proops,
Josie Lawrence, Brad Sherwood, Paul Merton, Sandi Toksvig,
Mike McShane, Chip Esten, Jim Sweeney, Steve Steen, Tony Slattery and Steve Frost, as well as
Ryan Stiles and Colin Mochrie who became fixtures of the later seasons.
These performers were joined by guests such as Stephen Fry, Rory Bremner, Graeme Garden, Jonathan Pryce, Ardal O'Hanlon, Mark Cohen, George Wendt and many more. A number of episodes were filmed in New York in 1991/92.
In 1998 the original show celebrated its 10th year by filming the series "In Hollywood". The cast then
joined a new host, Drew Carey, to tape a 6-episode pilot series for ABC with Ryan & Drew
as producers. Laura Hall provided music for both of these series.
The pilot run was successful, extended by an extra episode followed by a full series shown in a summer replacement slot. The US version, sometimes referred to by fans as DLiiA? (or "Drew's Line") has seen Wayne Brady join Ryan & Colin as regulars. Fourth-seaters have included the return of oldies Greg, Josie, Chip & Brad as well as newcomers including Kathy Greenwood, Denny Siegel and Jeff Davis. Laura has been joined by guitarist Linda Taylor and other musicians.
Robin Williams, Whoopi Goldberg and Stephen Colbert have appeared for episodes, whilst celebrities
including Jerry Springer, Florence Henderson, Sid Caesar, Hugh Hefner,
Richard Simmons, Chyna and even Lassie have joined for individual games.
In 2013, Whose Line was revived on television by The CW with Aisha Tyler as the new host. The three regulars have returned along with some past players, and new performers including Gary Anthony Williams, Heather Anne Campbell, Keegan-Michael Kay, Jonathan Mangum and Nyima Funk. The celebrity guest format has become a regular feature in the majority of episodes. The show has been renewed for further seasons.
