Here's where I'm coming from on this - I'm quoting from a convo I had with Karst one day along these same lines:
I run a bi-weekly trivia night here in Portland. We get 200 people at every one. And to settle ties, I bring down my fightsticks, boot up some Street Fighter, and that's how ties are broken. The number of people in this trivia night that have a passing knowledge of fighting games is MAYBE 7, if you don't count me. Yet it's become a legitimate attraction. People will show up and compete SIMPLY to watch the tiebreakers, and they are audibly upset when there aren't any.
And we're talking about SCRUBBY play. Super-scrubby. But even then, the attendees have started to pick out who is okay, who isn't, who probably deserves to get their shit wrecked - and there are now individual trivia players who have FANS when it comes to getting up in front of everybody and playing Street Fighter on a 30ft screen. And people have been (and still do) PRACTICE at home for the chance they might end up on that screen.
So if that sort of thing can organically happen, and appeal to a wide number of people who never even play the game, all without the help of what "Fighting Game Community" there is in this town (and they're here, they're just kinda insular and disorganized) - I have a hard time believing it's the genre of fighting games itself that limits viewership.
If anything, fighting games are way better built for this kinda stuff than Starcraft. You can get a sense for the individual players, their styles, their personalities. It makes it way easier to root for/against somebody. Way easier to invest.
There's a tremendous amount of potential being left on the table, and it's frustrating.
edit:
getting the fuck out of Spooky's way is solid advice. Or doing what you can to help the man. Either/or. Preferably both.
