Seems to me like Dish tv has been around forever while spaceX is just now providing internet via satellite, what took so long?

Satellite TV is a one-way process – the satellite beams data down, your dish catches it, and you play whatever is in that data on your screen.
Satellite Internet requires that you be able to send (quite a bit of) data back up to the satellite.
The same sort of delay happened between broadcast television (in the 1920s) and the corresponding mobile internet (in the 1990s)
