SERIES REVIVAL: This series began as a summer diversion for ABC in 1998, so it’s fitting that CW, in reviving the show, starts it during the summer months. The ABC version, hosted by Drew Carey, was popular enough to move to the regular series and run for six years. Carey is a daytime game-show host now, so Aisha Tyler is the new host, but the improv gang having all the fun remains the same: Ryan Styles, Wayne Brady and Colin Mochrie.
