Two years after launch Flip has 17% of the US camcorder market

"Within a few months, Pure Digital could barely keep up with orders. Customers found that the Flip was the perfect way to get homebrew videos onto the suddenly flourishing YouTube, and the camera became a megahit, selling more than 1 million units in its first year. Today—just two years later—the Flip Ultra and its subsequent revisions are the best-selling video cameras in the US, commanding 17 percent of the camcorder market. Sony and Canon are now scrambling to catch up."
