AT&T has filed a lawsuit against Verizon Wireless for the "There's a Map for That" advertising campaign, which pokes fun of Apple and AT&T's "There's an App for That" campaign. The heart of the issue is the AT&T 3G coverage map that Verizon Wireless shows in the commercials. AT&T claims that the large holes in the ad suggest that there is no coverage in those regions at all, and misleads consumers to think so. The lawsuit complains, "By communicating that AT&T customers have no coverage in large parts of the country, Verizon is misleading the public about an essential component of the services AT&T offers." The map used by Verizon shows only AT&T's 3G network footprint, and leaves blank spaces where AT&T provides EDGE coverage.
