Or as we say in CE parlance, "stuff way too far ahead".In other words ideas or gadgets that coulda/shoulda stuck around and made the entire industry copy it.I'll start with the Hitachi "media box".Back when, Hitachi had the great idea of selling the ATSC tuner separate from the display (everybody remember the Super Thin LCD and plasma?).You got your thin display (1.5" when everyone else was 3"+).And, if you didn't need it, you didn't have to buy the tuner. The display itself was equipped with 1 of each input. The tuner box upconverted to HDMI if you wanted it to.(at the time HDMI upconversion only existed on super expensive AVR, so your VCR etc could connect to the media box...)Bonus?The tuner box HDMI could go to your AVR, so...it could go with your AVR and eliminate the coax/toslink you would need from EVERY OTHER TV ON THE MARKET.Joe Public didn't get it.But, Samsung(who purchased Hitachi's production capability) brings this idea once again to their UHD sets...again, so they can be stupidly thin.Others?
