Over time some brand names are so well established in our daily lives that they become action verbs for things we do rather than proper names for things we use. For example, Xerox is not just a company, it's a procedure for duplicating paper documents and Google is not just a search engine, it's the action we take to find information. Pop Tarts and Chap Stick are registered trademarks for specific products, but they've evolved into catch-all for toaster pastries and lip balm, respectively.
