if only they'd make more slurm
Green cola (or a similar fizzy, sweet drink) with a can facelift would probably be worth Coke's time and investment to manufacture and sell as slurm, even if only for a limited run. Younger kids (even those who've never heard of Futurama) would gleefully guzzle down green ooze, and geeky shops would stock it (they'd probably sell out quickly, too). Heh, I bet university bars and the like would do a roaring trade in cans of "slurm".
It's just a question of the right distribution network, price point, and marketing strategy. Coke have the resources to pull it off, but it wouldn't exactly be "cornering a lucrative market" for them.
I know I'd drink something fizzy, sweet, and green in a slurm can rather than any of the pop/soda that you generally get all over the UK. I'd probably choose root beer over slurm, but we don't have much of that over here anyway. I don't think that for the sake of a piffling few hundred thousand pounds profit a year, Coke will do this though.
So, yeah, it'd be nice to see slurm rise to popularity in the real world, but it's probably not going to happen.
