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. Despicable Me 2 became available to purchase across digital retailers like iTunes, Amazon, and Comcasts 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, thats only two movies, so its impossible to truly say how widespread usage of Comcasts new service is just yet — but being the top retailer for a major new release like Despicable Me 2 certainly is a good start.
