Technical and cost factors make satellite basically uninteresting for most markets until Ka band comes out (there is limited use now, such as wild blue in USA, but the satellite with Ka coverage for Mideast was lost due to a launch problem with a rocket, and all other Ka capacity seems to go to HDTV broadcast vs data.

Personally the most interesting thing I see is O3b, which is maybe a year away.

Ku and L are good for limited markets, but just cost too much for YouTube users anywhere with terrestrial alternatives.

Bandwidth efficient protocols and proxies, combined with wifi and pirate gsm mesh networks, which can talk to unmodified laptops and cellphones for end users, are probably the best tech for situations like Egypt or post natural disaster.
