Goofing off eventually turned into a business. In 2007, Blackstock and Panth decided to start Bitstrips in an attempt to create a comic-strip version of YouTube. Bitstrips remained a novelty service confined to customizing comics within Web browsers until October, when the company released a mobile application for iPhones, iPads and devices running on Android software.
But Blackstock, 38, and Panth, 39, are getting the last laugh as their once-quirky pastime turns into a worldwide phenomenon. More than 30 million people in 90 countries have turned themselves into comic-book characters on Bitstrips' mobile applications. Google, which tracks people's interests through its widely used search engine, rated Bitstrips as the trendiest app of 2013, eclipsing the likes of Twitter's Vine video app, Facebook's Instragram photo app, King.com's Candy Crush game and SnapChat's ephemeral messaging app.
