Marketers have enough things to worry about these days. Just keeping up with new technology and ad formats is enough to drive most of them crazy. So let me add another worry to their list: the FTC. It’s a sizeable worry (sorry).In the last two years, the FTC has been very active in identifying companies who are using unfair and deceptive advertising practices and then fining them. We've heard of at least 10 different legal cases brought against advertisers since 2012. A particular one in 2012 resulted in an advertiser paying a $1 million fine and being forced to closely monitor its affiliates for future deceptive advertising practices.
