Most every point-and-shoot is capable of recording movies. What Casio does is uniquely partner with an exciting, successful business - YouTube. The popular video-sharing website appeals to everyone from the Star Wars Kid to presidential candidates.
For better or worse, Casio effectively matches its customers with an already recognizable brand name. Even more, the camera model name, itself, is already recognizable - who hasn’t heard of V8 drinks or V8 engines? The Casio Exilim Ex-V8 is much easier to remember than the four-numbered product numbers that modify Casio’s earlier Z-series cameras (eg. the Casio Exilim EX-Z1080).
It is genius on its part, making good on a strong coupling between the digital still camera world and the popularity of the website dedicated to personal video.
