Advanced television was talked about since around 1985 or so, when Sony came
out with it's 1125 equipment. Interest in HDTV peaked in 1987 with the
opening of 1125 Productions in New York. Then interest waned when it was
determined that analog HDTV would need 12 MHz of bandwidth, ala the NHK MUSE
system in Japan.
It wasn't until the advent of a digital system that allowed closer packing
of the TV frequencies, along with the explosion in wireless devices, that
gave the legislature ideas that they could then sell off spectrum that
things went beyond the talking stage. N'est pas?
