“PC Users with Netscape, Mozilla or Firefox: you need to run Internet Explorer to use MTV Overdrive,” so says MTV’s Broadband Video Channel site. Excuse us, MTV, but no, we don’t. Perhaps you haven’t heard that Firefox isn’t just this little side project that a bunch of geeks work on in their spare time in-between discussing episodes of Battlestar Galactica. It’s a full fledged, far superior to Internet Explorer, browser that’s gaining some serious market share. Marketers who continue to practice this loyal-to-Microsoft buffoonery are unsmart, unintelligent and losing out on a vast chunk of business.
