Arthur Levinson had a gig that many in the tech world would kill for. He was on the boards of both Google and Apple.

Sounds great, but then the Federal Trade Commission began investigating the cozy relationships between the boards of the two companies. I'm sure the commission had plenty of questions for Levinson.

So now, Levinson is leaving Google's board. This comes after Google's chief executive, Eric Schmidt, resigned from Apple's board in August.

It's unclear if Levinson left as a direct result of the FTC inquiry or some other issue with Google. But it sounded like Levinson had the full support of the search company.

Schmidt said earlier this month that Levinson should stay on both boards, and he gave a warm statement Monday praising Levinson after the news broke about his resignation.

Will the FTC go after Al Gore next? He's on Apple's board and serves as an advisor to Google as well.
