NPE (which stands for New Product Experimentation) was set up a few months back to work on, you guessed it, experimental Facebook apps. The team's previous efforts include Bump, a chat app that helps strangers connect over simple ice breaker questions, and Aux, a group listening app that lets you pick songs and compete for their group's virtual auxiliary cable. All three applications are targeting younger smartphone owners -- the type who are currently obsessed with TikTok and Twitch. While the Instagram team adds TikTok-inspired features to its app, it makes sense for Facebook to place a few smaller and arguably more original bets on mobile.

Will Whale ever be released worldwide? We wouldn't bet on it. Facebook is quick to launch experimental apps and even quicker to shut them down (remember Slingshot?) if they don't take off in their initial test markets.
