The late Philbin spent a great chunk of those 16,000+ hours on "Live with Regis and Kathy Lee" -- later "Live with Regis and Kelly" -- and "Who Wants to Be a Millionaire."
But his journey started from humble beginnings. After leaving the Navy, Philbin several odd jobs before landing his first on-air role as a fill-in sportscaster on a local Los Angeles TV station.
Here's a timeline of Regis's life and legacy:
1931: Regis Francis Xavier Philbin was born on August 25 and grew up in the New York borough of the Bronx.
1953: Philbin graduated from Notre Dame University and joined the Navy.
1955: Philbin talked his way into a meeting with the stationmaster at KCOP-TV in Los Angeles. He got a job parking cars, then progressed into work as a stagehand, courier, newswriter and producer of a sports telecast. When its sportscaster didn't show up one day, Philbin filled in.
1961: His first talk show, "The Regis Philbin Show," airs from KOGO-TV in San Diego to a national audience. The program of music and celebrity interviews was taped two weeks before each airing. It was canceled after four months.

1975-1981: He co-hosted "A.M. Los Angeles" on KABC-TV, first with Sarah Purcell and then Cyndy Garvey.

1988: Philbin and Gifford's show becomes nationally syndicated and renamed "Live with Regis and Kathie Lee." Celebrities routinely stopped by Philbin's morning show, but its heart was in the first 15 minutes when he and Gifford bantered about the events of the day.
