Electronic Arts Chief Financial Officer Eric Brown has unexpectedly left the company to join Polycom. Brown will take the role of both CFO and COO at the communications company.

"I am delighted to join Polycom at such an exciting time," said Brown, in a read-between-the-lines press release issued by his new employer. "With Polycom's software strategy, open platform approach, broad ecosystem of partners, and strong brand loyalty among its huge installed base, I believe the company is ideally poised to capitalize on this new model."

This ends Brown's second tour of duty at EA. He returned as CFO in 2008 after having previously left as Chief Operating Officer of EA's Redwood Shores Studio. CFO, COO... it appears Brown will continue his quest for that elusive vowel to become a CEO.

With Brown exiting, EA announced other changes to its executive team, including Mark Tonneson as SVP and Chief Information Officer. EA has "begun a search for a new CFO," with Ken Barker serving in the interim.
