AT&T did not file this lawsuit because Verizon’s ‘There’s A Map For That’ advertisements are untrue; AT&T sued because Verizon’s ads are true and the truth hurts.
Verizon in an official response to AT&T’s lawsuit that Verizon’s “there’s a map for that” ad campaign is misleading.
The background is that Verizon recently rolled out a campaign that uses a visualization of relational data to compare their 3G coverage to AT&T. The visualization is pretty stark. AT&T fired back that the ad was misleading, giving consumers the impression that AT&T doesn’t have ANY wireless coverage in most parts of the country.
Decide for yourself. FlowingData has a great recap post with all the ads to date.
