Via Carob (not a blog):
The International Trademark Association has a list of trademarks to help authors know when to capitalize things and how to punctuate them. This could be useful. I particularly like the possibility of getting generic terms.
Here’s a bit (hmm, where’s ‘Google’?)
Gold Top mantles for lanterns
Golf automobiles
Goobers chocolate covered peanuts
Good Housekeeping Seal of Approval certification Good Humor ice cream
Good & Plenty candy
Goodyear tires, blimp
Gordon’s gin and vodka
Gore-Tex water repellent fabric, outerwear
Gorham china, silverware, stemware, crystal
Got Milk? Milk Association slogan
Graduate Record Examinations tests, educational software (also GRE)
Graduates toddler foods
Grand Marnier cordials
GrandMa’s cookies
Grand Ole Opry country music program
Grape-Nuts cereal
GravyMaster seasonings
I suppose it’s only the ones used in English. After all, for example, Tippex in German is always capitalized. Is it purely US, with no British examples? It says 170 countries belong.
