I wonder if a company like Valve would ever consider merging with someone like Roku. You bring as much content to the consumer as possible, focusing on a la carte offerings that include movies, tv series, music, and of course games. On top of a la carte you could also offer bundle deals.
As a result of bringing all of this media streaming and downloading together, you might also force internet companies to offer discounts to their customers as you can help control the issue of bandwidth with a Roku membership.
