OMGPOP has had a rough life under Zynga's wing -- the startup fell from grace as it became clear that Draw Something was more a one-hit wonder than a sustainable profit engine. It makes sense, then, that Zynga is continuing its cost-cutting spree with plans to close OMGPOP's less successful web portal. The shutdown will start with four of OMGPOP's web games, which stop running on August 29th. OMGPOP.com will go dark a month later, on September 30th. Only mobile apps will remain after the closure, including Draw Something, Draw Something 2 and Draw My Thing. The move isn't surprising given Zynga's strengthened mobile focus, but we're still sad to see OMGPOP lose a large part of its remaining identity.
