Here are a few... DIVX, the original implementation.
Circuit City and some Hollywood studio law firms conspired to make disposable DVDs that only allowed a certain number of days to view once initialized.
At first, Disney movies were ONLY going to be on the DIVX format.
ProScan, RCA and a couple others made "Divx enhanced" DVD players for the first 3-4 years of DVD.
Check out the firsts from Zenith.... First with the remote. Developed the accepted standard for Stereo on FM radio broadcasts... Developed the accepted standard for MTS Stereo on broadcast TV.....
They had about a dozen other major firsts. At one point, Zenith held more HDTV technology patents and drafted more standards contributing to the new format than anyone....http://www.zenith.com/index.asp?url=...bout_index.asp
Zenith and RCA stuck it out with television manufacturing in the US long after everyone else left. Zenith is now owned by LG, and RCA is now owned by GE....
Mark Cuban and the HD Net... HD on mainstream cable and sat would not be where it is today w/out the crazy Billionaire out there subsidizing uber expensive HD rigs traveling around taping anything and everything in HD.
Also, where is satellite in general?? start with the big dish systems...
C band... K band... later (1989?) came Ku band which worked on a then unheard of 36" dish...
How about DSS??
RCA had a one year exclusivity clause on DSS, and the early years had two subsription services, DirecTV (who had the "basic cable" type channels) and USSB (which is where the Premium channels existed) USSB was acquired by DirecTV within a couple years.
Dish Network was launched by Echostar, who were also providers of big dish electrronics.
Prime Star was another DSS competitor, eventually acquired by DirecTV
Also, anyone remember Unity Motion?? (RIP) The original HDTV satellite system....http://www.businessweek.com/1998/43/b3601011.htm
Where is the invention of TiVo?? Philips had that sewn up for a year or so before the Sony and Tivo branded units arrived. IMO, this is probably the most important consumer electronics creation involving TV since color.
