I think Bose's genius was taking the 'plastic crap' consumer level junk disposable electronics for people that would never spend the time (or money) to invest in serious gear* to another level- stylized, 'lifestyle' components that people instantly recognize by name- down a notch or two or more from companies like B & 0 but cheaper too- and commercializing the hell out of it- for add-ons to TV systems without the hassle of using a more involved HT audio system, table radios (H Kloss did a nice job with those too, back in the KLH and Advent days), etc.
Did Starbucks invent the coffee shop- I don't think so, but try and think of an espresso bar/coffee store today without Starbucks- they reinvented the concept by borrowing from 'real' coffee bars and institutionalizing it broadly. I think their coffee sucks (their espresso shots are OK, and cheap), and in that sense, they 'invented' something.

*And rightly so, most average stiffs aren't going to invest in an audio processor, separate basic amps, high quality speakers, subwoofer systems, etc. for the TV. Even the HT 'receiver,' which isn't "serious gear," is more of an investment than most folks probably want to make to get surround for their TV. And, today, given the fact that most 20 somethings watch movies on their computers, the idea of a full-on HT system doesn't make any sense.
