But with Android devices growing and Google continuing to push its own Google Play marketplace, it seemed well worth including in this survey. Google Play is probably still in the 'Other' category. The first four video marketplaces were listed yesterday by NPD as among the top ways people purchase digital video. In this column, I look at how 'trapped' video content purchased from iTunes, Amazon, Vudu, Xbox and Google Play may be. But one of the biggest downsides of going all digital is that how you can view your content is largely dependent on the service you purchased it from. Have you decided to ditch DVDs and Blu-rays to instead buy movies and TV shows only in a pure digital format?
