At this point, Barnes & Noble isn't fashionably late to the streaming video party, it's just downright late. Better late than never, though, right? Along that line of thinking, B&N today announced its Nook Video service, which will premier sometime this fall. B&N already has movies and TV shows lined up from major studios, including HBO, Sony Pictures Home Entertainment, STARZ, Viacom, and Warner Bros. Entertainment, to name a few. The service will also stream select Disney titles, the company said.
