Synonyms

Some companies are so powerful that their brand name becomes synonymous with their product. Here is a list of examples I've been working on for some time now. Feel free to add to my list as a comment.

Kleenex
White Out
Post It
Rolodex
Ball Point pen
Scotch tape
Frisbee
Yellow pages
Sharpie
Lancet
Velcro
Tums
Highlighter
Jello
Chap Stick

Even if you don't buy the Kleenex brand... you still call them Kleenex, not facial tissue. It's ingenious!
