While Comcast has long offered movie rentals through its various on-demand cable services, we were a little surprised to see the provider start offering the ability to purchase digital movies and keep them forever. But it sounds like the new Xfinity On Demand store is a success so far, at least according to one limited metric. Despicable Me 2 became available to purchase across digital retailers like iTunes, Amazon, and Comcast's Xfinity service on November 26th — and Comcast says that it was the number one purchase destination during that first week of availability. Comcast also says that it was the top destination that week (as well as the week prior) for those looking to buy The Hunger Games, a movie obviously buoyed by its recently-released sequel.

Of course, that's only two movies, so it's impossible to truly say how widespread usage of Comcast's new service is just yet — but being the top retailer for a major new release like Despicable Me 2 certainly is a good start. It does seem that Comcast did some things right with its service, including the ability to download files for offline viewing, mobile support, and — perhaps most importantly — the ability to transfer your purchases away from your Comcast account if you happen to switch cable providers.
