GFCI has also been required in kitchens 6 Ft from the sink since the mid 80's, and then amended to all counter-top plugs since the mid 90's.
True dat.
http://ecmweb.com/nec/code-basics/electric_code_basics_3/Although, as I stated earlier, even if it APPEARS that something isn't GFCI, it may be in series with an outlet which is, and that's perfectly legal.
And I double-checked the NEC, so yeah, it's been six feet, then all, for quite some time. Damn old code. Teach me to go from memory and say three feet.
These are the locations in and around the home when GFCIs were first required:
1968 - Swimming Pool Underwater Lighting
1971 - Receptacles Near Swimming Pools
1973 - Outdoor Receptacles
1975 - Bathroom Receptacles
1978 - Garage Receptacles
