Question: All of the ones I can think of are specific products that have come to represent their kind. This is usually either because it is the first of its kind, as in a Xerox machine (the first office photocopier), or it arises from popularity, as in Sharpie or something like "Google that" (though I'd say that's a bit informal/debatable).

Other examples I can think of off the top of my head are:

* Kleenex
* Post-it

Answer: 
* Duck tape
* George Foreman grill
* Palm Pilot
* Scotch tape
Some of the words that I find in common use nowadays in their domain are as follows:

> 1. Blogging (Posting articles on web-logs)
> 2. Magging (Shooting)
> 3. Facebooking (Online on facebook)
