As of this writing, Akbank's Facebook page has 508,397 fans. The bank itself has 913 branches serving 8 million customers, and they've been managing a total of 15 social media accounts between Facebook, Twitter, and YouTube. They've also created 5 Facebook applications, some of which, are games promoting their brand.
One of these games, Kur Yönet, which translates into "Manage the Exchange Rate", allows users to build a virtual factory that involves everything from production to marketing to R&D. All banking, of course, is handled by the Akbank branch within the game.
Aside from these two, there's also been a music trivia page offering free concert tickets that was targeted at the youth, a gift cards giveaway page on applying for personal loans, and another trivia game involving current events in Turkish history that later tells players how much money they could've made if only they opened a Cumulative Mutual Fund account on a certain date. These are all a bit of a stretch, but Akbank seems completely devoted to pushing their brand, wherever, whenever, and however possible. Moreover, it appears that all their efforts have paid off.
