What If Blockbuster Had Bought Netflix?

Felix Salmon cautions:

Buying internet companies is very, very hard: even if they are set to be very successful on their own, that’s no reason to believe that they will have similar success in-house. Google bought Foursquare back in 2005, when it was called Dodgeball, but then closed it down; only when its founders left Google and recreated the company as Foursquare on their own were they able to succeed.
