Michael Cieply for The New York Times:
The Interview generated roughly $15 million in online sales and rentals during its first four days of availability, Sony Pictures said on Sunday. Sony did not say how much of that total represented $6 digital rentals versus $15 sales. The studio said there were about two million transactions over all.
Stas, with a zinger for the ages:
Probably they took advice from this guy.
Maybe an opening question to this problem would be:. Do you think Sony had more rentals or more sales? This could lead to some interesting discussions before actually solving the problem.
