AppStrip是由中型Facebook开发公司Broken Bulb Studios开发的一款跨游戏宣传工具。与竞争对手Applifier类似，AppStrip也是位于社交游戏上方或下方的一条简化横条工具栏，介绍宣传其他各种社交游戏。
目前Broken Bulb Studios尚未发布关于这则消息的更多信息，或许Broken Bulb Studios认为AppStrip的发展不如预计因此决定将其出售。据今年9月统计，Applifier网站用户约为5000万人，而AppStrip用户只在1000万左右徘徊。（更新：有消息称AppStrip用户远高于1000万）。
We’ve just learned that Tapjoy, formerly Offerpal, has bought the social gaming cross-promotion service AppStrip. Charles Hudson first spotted the news, and was quickly followed by a TapJoy blog post.
AppStrip was created by Broken Bulb Studios, a mid-sized Facebook developer. Like Applifier, which the service was started to compete with, AppStrip is a simple bar that sits above or below a social game, containing links out to other games.
Two factors have made both Applifier and AppStrip successful. The first, and most important, is that Facebook’s viral channels have been becoming less effective, leaving advertising or cross-promotion as the only alternatives.
Second, the two promotion bars are mostly quid pro quo — if your game can send a user out, it will automatically get one back from the network for free. Most developers that aren’t large enough to run a cross-promo network from their own apps alone thus install one or the other bar.
Neither company has given us any further information yet, but it’s possible that Broken Bulb decided AppStrip wasn’t growing quickly enough to keep.
While Applifier had well over 50 million users in its network in September, and likely more today, AppStrip’s network appears to be hovering at around 10 million users, by our back-of-the-envelope count [Update: we now hear that number is far too low, more on this tomorrow].
It’s also not clear yet whether TapJoy plans to change AppStrip, but the bar does complement SocialKast, a service that TapJoy launched in July to promote apps across different social networks. （Source：Inside Social Games）
