I saw a link for this and thought I’d find out more. I imagine that if everybody in America bought a FOXBlocker, the average IQ would go up about 10 points. This is simply an inline cable filter. While the device itself doesn’t really do any more than my never watching that channel; the company sends an e‑mail to Fox’s top 10 advertisers letting them know there’s one less customer in that market. No that would make a dent. I suppose at some point the marketing gurus there would figure out that anyone who bought one was probably already watching the BBC News, PBS, or just listening to NPR because they never had cable in the first place.
