When all is said and done there’s going to be a few players left and they’re all going to be American by the current looks of things. You could argue movies were already like this, but for television that’s quite the change as most countries had many television production companies and stations.
Now it seems like they’ll be a few global media companies and maybe some local production houses that have to sell their stuff to these guys or setup their own services like the BBC does with iPlayer in the UK, with somewhat limited success compared to these giants.
