Larry King is a broadcasting institution.

Tens of thousands of interviews, more than half a century on the air.

The famous and the infamous, the scandal-plagued and the powerful - they've all told their stories to Larry.

As a kid, Larry dreamed of working in radio, but didn't have the grades to go to college.

So, he hoofed it to Miami at 22 and landed a gig doing odd-jobs at a small radio station.

When an announcer walked off the job, Larry ended up on-air for the first time.

That was May 1st, 1957.

Over the next decade, he built his reputation - interviewing the likes of Jackie Gleason, Malcolm X, and Martin Luther King.

But Larry was a gambler and a big spender and in the early 70's he plead no contest to passing bad cheques.

But Laryy bounced back - eventually landing a national late night radio call-in show.

That led to his move to TV and the launch of 'Larry King Live' in 1985.

The show was a hit and Larry became one of CNN's first stars.

But it hasn't always been easy - in '87, he suffered a life-changing heart attack and over the years he's been married seven times to six women - with kids ranging in age from 8 to 50.

He tells the whole story in his new autobiography 'My Remarkable Journey.'
