Yahoo CEO Carol Bartz was right by the Reuters office this morning, ringing the morning bell at Nasdaq on 43rd Street and Broadway, so I ran down to catch a glimpse and lob a few questions at her. With all the buzz about Yahoo’s new marketing campaign, which is set to be unveiled tomorrow, I asked Bartz if she was excited.

“Excited? I’m so excited about it, I could do a Yahoo yodel,” she said. But then, she didn’t oblige. Bartz did say New Yorkers will see splashy Yahoo signs and other gimmicks over the next few days. But it’s not just New York.

The campaign, which the New York Times says is backed by a $100 million budget, will be launched all over the world, Bartz said. We’ll have more on Tuesday, when Yahoo executives tell reporters what they are up to. Until then, here’s a sneak peak courtesy of The Wall Street Journal, which says the campaign tagline is “It’s You!”.
