AT&T is suing Verizon over the latter's "There's a map for that" campaign. The ads, by McCann Erickson in New York, show competing red and blue maps to show how much more 3G coverage Verizon offers than AT&T. But AT&T, the nation's No. 2 wireless carrier, is worred that people will interpret the blank spots on its map as areas where AT&T has no coverage at all, which it says isn't true. (It's not an apples-to-apples comparison of their 3G networks, the company says.) AT&T's outcry has resulted in much public scrutiny and attention over the ads—and lots of free publicity for category leader Verizon.
