A:Answer ROKU comes with hundreds of free channels, many without commercials. Free movies, shows, everything on earth. Unlike Samsung's platform and some other closed platforms, you can add any other service or application, and you can find one perfect for you. (ROKU can run on Samsung TVs and other closed platforms.) As far as local channels, most all modern TVs have several HDMI inputs. You plug in the ROKU to one HDMI slot, and use another HDMI slot for an antenna and get regular local channels, UHF, etc. (No more rabbit ears; digital antennas cost a one time fee of $30.).
