Regis Philbin is retiring from Live with Regis and Kelly. He made the announcement this morning on the daily syndicated talk show, which he has been hosting for almost 25 years. Live will continue after his departure, slated for late summer or fall, with Kelly Ripa getting a new co-host. Philbin, who is 79, has been in television for a half a century, with his numerous gigs including hosting the American version of Who Wants to be a Millionaire. Live originated as The Morning Show on WABC-TV with him and Cindy Garvey as co-hosts. Kathie Lee Gifford became his co-host in 1985, and in 1988, Buena Vista Television launched the syndicated Live with Regis & Kathie Lee. Gifford departed the show in 2000, with Ripa joining the show in 2001. In the past few years, Philbin underwent a heart bypass and hip replacement surgeries. Philbin holds the world record for most hours spent in front of a TV camera with well over 16,000 hours on the air.
