omgpopAlmost exactly a year after Zynga bought one-hit wonder OMGPOP for a cool $200 million, OMGPOP chief executive Dan Porter has been replaced by Zynga VP Sean Kelly, reports BetaBeat in a tweet:

At the time of Zynga’s acquisition, OMGPOP had 20.5 million daily active users and 37 million installs, and was the most-tweeted game ever. Of course, since, Zynga stock has cratered, OMGPOP’s chief revenue officer left, and the hits have not been fast and furious.

Zynga COO David Ko confirmed the departure in an email to VentureBeat, saying:

“Developing and launching games is a team effort, and we’re proud of the great work the Zynga New York team has done with Draw Something 2.

Our follow up to the original hit is even more social and engaging, and we’re excited to get it into the hands of our players globally.  We thank Dan Porter for his efforts in making the Draw Something franchise a success and wish him well in his future endeavors.

We’re proud to see talent like Sean Kelly take a bigger leadership role as the Head of our New York studio and lead the team to the global launch of Draw Something 2.”
