“Regis is in the same category as Carson.

Superlative,” he wrote, according toPeople.

When he retired I lost interest in television.

I love him."

The TV world can be a difficult place to work, particularly when you’re first starting out.

The former TV show host “never got on some high horse about anything,” Vieira said.

“He said, ‘You’re going to be great, kid.

Just be yourself,'” Vieira revealed.

That was very liberating and I’m sure he knew that."
