I've also seen a company advertising on TV - the advert starts with asking who invented the vacuum cleaner giving the options of professor, scientist or caretaker. The answer is the caretaker and then they tell you all about how so many things were invented by the 'ordinary' public. Be careful though, as one of my friends had an invention and wrote off to one of these companies who wrote back saying his idea was brilliant, they'd never heard anything like it and wanted to pursue it. Then they ask you for lots of money to support promotion sales in supermarkets etc, then there's the patents. I don't want to dampen your spirits, but just tread carefully. There's a show on cable called Whats the Big Idea which moves around the country doing shows where people can show ideas to experts, they'll check if there's another invention like it and you can get the chance for a company to back you and invest in your idea. Try looking it up on the net. Hope that helps! :)
