Electronic Arts is set to purchase PopCap Games for $1 billion, according to TechCrunch. PopCap Games is best known for titles such as Plants vs. Zombies, Peggle, and Bejewled, all of which are available on a number of platforms, including the PC and mobile devices. It’s unclear what the motivation behind the purchase is. EA has a number of hits available in the iTunes App Store, including NBA Jam, The Sims, and Tiger Woods PGA Tour 12, but perhaps it could use PopCap’s expertise in the casual market to create an entity capable of competing with the likes of Zynga — a firm that relies on in-game purchases to make money. Neither Electronic Arts nor PopCap Games has confirmed the purchase.
