It appears that Sony is outwitting competing game consoles and set top boxes in the Netflix streaming world, as Netflix revealed that its subscribers view content on the PlayStation 3 more often than any other device in the living room. This is ahead of of the Xbox 360, Apple TV, and the Roku boxes.
It even occasionally surpassed PC usage of Netflix, but currently that is not the case. Netflix has come a bit of ways since it's original launch. For one, you no longer have to use a special Blu-Ray disc to watch movies.
If you have Netflix but do not have it on the PS3 currently, you can download the official app for free from the PlayStation Store under the "Media and Apps" section. You can also grab other streaming applications as well if you use other streaming services. You also have a few apps to download as well from that section that are not related to streaming.
