We've known Best Buy's CinemaNow-branded streaming service was in the works for some time now, but it's finally launching this month. At the moment, this only concerns those of you with an LG Blu-ray player, since you'll have access to $3-$4 rentals (and more expensive purchases) first. As the service is refined, it will make itself available across platforms, much like Netflix and all of those other streaming services you probably don't use. [WSJ]
