I attended Steve Jobs Tokyo introduction of the NeXT Computer, around 1990. It was very cool and inspiring.
The guys at ID Software trudged threw the snow to get a NeXT computer and soon after came up with DOOM. The first web server was developed on a NeXT computer. The NeXT Computer was some kind of catalyst.
Around that time Steve said multimedia was a "Zero Billion Dollar Business". He meant there was no money in it. It has a different meaning today. But, in the last week or so "Call of Duty: Black Ops" (a modern DOOM like game) has become the biggest grossing first day release of anything of all time.
We call computer based stuff like that multimedia. I think history has shown that Steve's interpretation of what multimedia was, wasn't correct. Apple for longest time hadn't thought the game market was significant either.
If it had been, would the NeXT Computer still be around? Would many more cool things have been developed, by people that have since been sidetracked posting trivia from their iPhones to Twitter and Facebook?
