By December 1, 2007, licensees of commercial and noncommercial digital television stations must file an FCC Form 317 electronically reporting on whether the station has provided any ancillary and supplementary services during the twelve-month period ending on September 30, 2007.  If the station did provide such services and generated any revenue from such services, then the FCC wants to know about it.  More importantly, the FCC wants its 5% cut of the gross revenues derived from such service.  Currently, only licensees are required to file the Form 317, so stations that do not yet hold a DTV license for some reason are not required to file.  The form is very brief, soliciting information about the license and the types of services provided, if any, and must be filed electronically through CDBS.
