Right now, companies like Facebook and Google are working on bringing the internet to countries that don't have good access to it yet; if it wasn't for the lag (and cost), I'm sure they would've invested heavily into a sattelite internet network.

I see a small / niche market in space tourism; Virgin Intergalactic is probably going to get on there. But it'll be limited to those that can shell out 100K for it.

There was some talk about a company a few years back that wanted to mine asteroids; I personally think that's science fiction and won't be a profitable endeavour, but, if I'm wrong, it'll unleash a new kind of corporate space race.

I think it can go very fast if there's enough money to be made. As it stands though, besides satellites, there is nothing to be had.
