Call it an "acqui-hire."
Apple has snapped up Particle, a San Francisco-based creative consulting company that specializes in Web applications and marketing projects using HTML5, CNET has learned.
Particle was founded in early 2008 and has some celebrity financial backing. Pop star-turned-actor Justin Timberlake is an investor and helped fund short social video service Robo.to, which Particle created. Sources with knowledge of the deal did not know the selling price.
