In response to Verizon’s “There’s a map for that” ad campaign, which riffed on the iPhones “There’s an app for that” campaign, iPhone mothership AT and T sued Verizon. The primary legal basis for AT and T’s claims was that the Verizon “There’s a map for that” map showed Verizon’s 3G coverage compared to AT and T’s 3G coverage in the same area – AT and T’s 3G coverage in those areas was much more limited (naturally, otherwise Verizon wouldn’t be using it in an ad campaign), and AT and T was complaining that they still have voice and data services in those areas (just not 3G) and so viewers could be mislead into thinking that AT and T didn’t have any coverage (not just 3G coverage) in the regions depicted.
