When you pass through Times Square, get in a cab, or go down into the subway, the number of screens you pass are endless. And some of those screens contain digital ads that are in front of pedestrians every day. This style of advertising is called digital out-of-home, and Barry Frey thinks it is the future of digital advertising. Barry Frey, CEO of Digital Place-based Advertising Association, joins Cheddar to explain how digital out-of-home advertising is on the rise. Some of the well-known examples are Taxi TV, elevator screens, and the LinkNYC wifi stands. Frey believes it is a viable alternative to advertising on Facebook and Google. Overall, digital out-of-home advertising is still only a portion of the advertising market. There is a potential for even more growth as businesses look for alternative ways to reach their consumers.
