When the TG-16 was launched in 1982, under the codename Panther, it forced the NES to do a "quick launch" about a month early in Yemen. After testing this market, nintendo knew it had a gem on thier hands. With nintendos deep pockets and NEC's marketing brilliance, they teamed up with philips to develop the CD unit. This took sega by surprise while they were scrambling to resurrect the failing genesis. By 1987, the third party license disagreement lead to nintendo splitting off and taking all the good licenses with them in draconian fashion. NEC counter punched by selling the CD technology to the video game juggernaut that was Atari, which eventually became the jaguar CD. Atari had 87% market share from 1990-1995 and nintendo/sega couldn't keep up. When NEC finally liquidated everything to Pepsi, thats when sony came along and said "we gotta get in this". Sony developed a new 3GB storage capacity cartridge which was going to usher in the next generation of video games. Too bad Danny Ocean stole the blueprints and sony was stuck with mediocre CD games in double CD cases. If it wasnt for that extra packaging (cost), sony would still be "in the game".
