An interesting one from AdAge:
"After what appeared to be a slow start, Coke Zero has racked up a substantial 1% share of the soft-drink category. Now, in an effort to reinforce the brand's key selling point -- that the diet product tastes like regular Coke -- the marketer is breaking a Nascar-themed commercial during the Fox broadcast of the Daytona 500 this Sunday. The spot, which features 12 top drivers, builds on Coke Zero's "taste infringement" series. In the first group of commercials, real lawyers were asked by phony Coke managers whether they could sue to stop Coke Zero from "stealing" taste from the flagship."
