DRTV has become a very popular way to advertise a product. Memorably, infomercials were seen late at night by smaller audiences. Today, infomercials are used by large established companies, small start up companies and even during Presidential campaigns. They are also no longer only viewed late at night. There are infomercials during prime time hours as well as weekends, early morning and afternoons. Infomercials have grown greatly in the past few years because the response they receive is real. Response to an infomercial can be tracked in real-time.
