Carnival will be the only cruise line to advertise during the 2010 Winter Olympics, the line said today.

Carnival also is debuting a new television advertising campaign today that features three spots retaining the brand's "Fun For All. All For Fun" tagline.

The new spots feature a voiceover provided by actor John Krasinski from NBC sitcom "The Office".

The new ads will run throughout the 17 days of Olympics broadcasting on NBC, MSNBC, CNBC and USA, Carnival said.

Carnival will be the exclusive sponsor of the athletes' section on NBCOlympics.com, featuring videos of the competitors.

The first TV spot can be viewed here.
