When Sony bought the cloud gaming service, Gaikai, in July of 2012 for $380 million, many in the industry were left scratching their heads. When PlayStation Now, their cloud-based video game streaming service, launched a little over a month ago on the PlayStation 4, people suddenly understood this purchase: the polished Gaikai tech (developed by industry legend David Perry) was under the hood of PS Now.

Sony is now reporting that it has expanded this service to a much wider audience. Although still in beta, PS Now has launched on PlayStation 3, so you'll be able to "rent" PlayStation 3 titles via streaming in "mainland U.S. and parts of Canada." The library of PS Now games has grown to more than 150 titles, and will continue to grow as the service expands over time. PS Now also offers a variety of rental periods depending on the game, and in most cases, you can rent a game for an entire week for approximately $1 per day.

Unfortunately, the feedback for PS Now has been less than positive as many feel the prices are too high. With the service now available to many additional core users (the PS3 still has a wider install base), one would think that Sony will be receiving a good bit more constructive feedback to help improve the service going forward.
