The Harmonix net loss to Viacom from discontinued operations for the nine months ended September 30 was $316 million, according to financial statements.

The company had high hopes for the launch of its "The Beatles" game in 2009, but Gould said that "didn't do anywhere near the kind of business they thought it was going to do."

Columbus Nova, which created Harmonix-SBE Holdings to hold the asset, is a multi-strategy investment firm managing over $10 billion of assets through its own funds and affiliated portfolio companies.

"Columbus Nova is really excited about backing the world-class team that has consistently produced such great games and helping them grow the company and its brands," a company spokesperson said in a statement.
