Pangea Media, the company behind social media marketing platform SnapApp, this morning announced that it has sold off its legacy website quiz and sweepstakes business to digital advertising firm Adknowledge.

Financial terms of the deal were not disclosed.

Pangea Media says it wants to focus on its SnapApp platform, which allows brands, publishers and agencies to interact with customers by setting up mini-quizzes, surveys and contests for use on websites, mobile apps and social networks.

Companies use SnapApp to collect leads and increase registrations, Facebook likes, new Twitter followers and whatnot.

Pangea Media was founded by CEO Seth Lieberman, who previously co-founded Focalex, an online advertising and direct marketing company that was sold to Intermix (the original parent company of MySpace) in November 2004.

Adknowledge did not specify why it acquired the quiz and sweepstakes business from Pangea Media, but the company often buys smaller firms or assets from relevant companies to enhance its own online advertising offerings.
