It's pinning its hopes on new ads, juiced-up old lines, and just a few fresh products -- in other words, business as usual. Why isn't it copying PepsiCo and making acquisitions?

Quick, what's Coca-Cola's (KO) current ad slogan? Hmm, had to think for a minute, didn't you? "Coke is it?" Sorry, that was the jingle used back in the 1980s and early 1990s. "Always?" Apparently not. That was retired in 1999.

You probably didn't guess "Real," and that says plenty about Coke's recent woes. The venerable beverage giant hasn't had an unforgettable marketing campaign for quite some time. And even the individual commercial spots are hit or miss. While the Diet Coke ads featuring a young girl skating along the beach were uplifting, the spots showing teens taking the train back from a concert were too somber, and the one with a teen rubbing a Coke can under his armpit were disgusting to anyone but 14-year-old boys.
