I'm a pretty hardcore PC gamer, but I can't believe that Steam, Valve Software's online distribution service wasn't mentioned. More content is being added all the time, from Valve itself, Activision, Popcap, 2K Games, Strategy First, and everyone's favorite indie developer, Introversion Software (the geniuses behind Uplink, Darwinia and Defcon)
Steam was criticised early in its existence for many problems such as bugs, but these days it is a pretty good piece of software, and is probably the best example of a successful online game store.
