Some "experts" believe that broadcast television (TV) is effectively dead, but in the last couple years there has been work done to re-invent over-the-air transmission in what spectrum has not yet been yielded to White Space for other uses. One of the major hurdles to overcome is how to service mobile devices that, if the effort is to succeed, must be able to work acceptably in the presence of a constantly moving receiver and the multipath phenomenon. Of course HDTV (high definition) will be expected by viewers so that adds to the difficulty. There are some grand plans for interactivity and on-demand programming that is not even available today to traditional household TV viewers.
There are many new services vying to operate in the newly available White Spacesluding new cell bands, security, surveillance, and other such things. Ever ready and willing to provide the electronics, hardware, firmware, and software to enable an army of inventors and investors, White Space, HDTV, and re-purposed broadcast television vendors are scrambling to be first to market. Some of those companies are listed here.
