Over 70 percent of people who use Facebook for iPad played a Facebook-connected game in the past 90 days, so the company is helping them discover or re-engage with games through a new home page sidebar it starts testing today on its iPad app. It includes social notifications for native mobile and Facebook web games you already play, video trailers for games you don’t, plus Trending news articles and Trending videos popular with your demographic. The growth opportunities could entice more developers to integrate Facebook into their games, and Facebook plans to eventually sell ads for games in this space. By filling the extra screen space with what tablet users love, Facebook hopes its home on iPad can become a more essential part of people’s live…even if that means bouncing them into other apps or showing them YouTube videos.
