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

Left out Jacuzzi - the generic term is hot tub; and perhaps fridge, which according to the Online Etymological Dictionary is:

shortened and altered form of refrigerator, 1926, perhaps influenced by Frigidaire (1919), a popular early brand name of the appliances.

I think the generic usage of "duck tape" as a distortion of "duct tape" actually predates the manufacture of the Duck Tape brand of duct tape. It's actually the phenomenon OP is asking about in reverse. –  chaos Feb 16 '11 at 8:42

Not completely; I'm dubious of the "duck tape" origin, though hey, could be. But even if it's true, it's an origin in a generic, not in the current Duck Tape trademarked product. Duck Products only even claims to go back 20 years. –  chaos Feb 16 '11 at 8:48

Scotch tape is US usage; in UK it would usually be called Sellotape. –  chimp Feb 16 '11 at 10:11

@chimp I hear that it is called Durex in Australia - which must lead to some interesting misunderstandings. –  MikeJ-UK Feb 16 '11 at 12:20

Why would "George Foreman grill" be generic? I've never heard it used to refer to random grills. –  John C Oct 9 '11 at 14:43
  • iPod (I've seen many people use iPod to refer to any MP3 player)
  • Xerox
  • Zip-lock

What you are looking for is called a genericized trademark, generic trademark, or proprietary eponym, and Wikipedia has a huge list:

It includes all the examples mentioned by chaos and yourself, and many more.

+1 for a comprehensive answer. The Wikipedia link also covers something I was thinking of... that the usage of many of these generic trademarks may be country-specific. For instance, though I call post-its post-its, I don't call facial tissues kleenex or vacuum cleaners hoovers. –  Tragicomic Feb 16 '11 at 10:25

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)

I think these are just general neologisms. Nobody ever had a trademark on "blog", did they? Facebooking isn't a generic; nobody would say they're Facebooking while they're on Myspace. –  chaos Feb 16 '11 at 8:46
    
I just meant that these are some words that are turning familiar. And yes the word "Blog" is a trademark. –  ikartik90 Feb 16 '11 at 8:54
