Online game-maker Zynga's founder and former chief executive Mark Pincus is stepping down as chief product officer as the company's sales slide.
Zynga yesterday said Pincus would remain chairman of the company he founded in 2007.
Zynga went public in 2011 on the strength of games like Farmville and Mafia Wars, which had enthusiastic Facebook followings. But rival digital game-makers invaded Facebook and more people migrated to other pastimes on smartphones.
Zynga has been cutting jobs and posting losses and the company is trying to shake things up.
Don Mattrick, who had been in charge of Microsoft's interactive entertainment division, replaced Pincus as CEO in July.
