In the latest of a string of heated telecom advertising disputes, the National Advertising Division (NAD) delivered a victory to T-Mobile US, Inc. (“T-Mobile”) in its challenge of claims made by Charter Communications Inc. (“Charter”). Charter’s claims involved a series of television commercials and website advertising insinuating that T-Mobile’s home internet service was slow, spotty, and glitchy—and more generally an untenable option for a typical family. T-Mobile alleged that these claims were false and denigrating. NAD, unsurprisingly, agreed with the challenger.
