Zynga's (ZNGA) marketing chief resigns after a year on the job

• 8th Zynga manager to leave since early August 2012

The departure of senior talent at online video games purveyor Zynga (ZNGA) continues this afternoon as the company announced in a filing with the Securities & Exchange Commission that its chief marketing officer, Jeff Karp, resigned.

Karp’s departure follows the departure of its chief creative officer, Mike Verdu, last month, followed almost immediately by the departure of its VP of studios, Bill Mooney, and vice president of marketing Brian Birtwistle.

Zynga has classically made much of its revenue from games hosted on Facebook (FB), though it has attempted to broaden its appeal to games it hosts directly on line through its own properties.

Zynga stock is off 2 cents, or 0.7%, at $2.80 in late trading.

Update: In a statement released this afternoon, subsequent to the filing, Zynga commented as follows:

Jeff Karp is leaving Zynga, and the groups in his organization have been realigned under appropriate existing divisions. Our marketing and revenue teams have always been industry leaders, and as we continue our transition toward mobile and multiplatform game creation and distribution, their continued execution will be key to our future success.  We are grateful to Jeff for his contributions over the last year and wish him well in his future endeavors.
