Howard TV was announced on August 4, 2005. At the time it didn't have a name. Howard alternated between calling in On Demand or In Demand, he could never properly figure it out. Someone suggested that the station be called Howard TV so that he would never forget what it's called when cross promoting it on his radio program.
Howard TV's main feature is an edited look at some of the events that take place on Howard's radio program. They also showcase hour long specials on people within the large family of Howard Stern personalities. At times the crew go back in the archives and show older E! Television shows that were originally aired in edited half hour segments in their unedited and non mosaic filtered glory.
It is considered a premium channel all unto itself. You need to have cable television to access Howard TV, satellite(ironically) television does not have access to the On Demand features, that is why you cannot see the shows.
