I don't know of any good reason to call them Edison. He didn't invent any kind of plug and receptacle.  He invented a home lighting system. Generation, distribution (BTW with two hot conductors sharing one neutral,) house wiring including fuses, and light fixtures with the screw in lamp base we use today.  He even trained the first home electricians.  He did a lot but he was designing a system to compete with gas lighting. He didn't think of small appliances or portable lighting.

The Plug or plug cap was invented by Hubbell in 1903  (He also invented the pull chain lamp socket)  The U ground plug was invented by Philip F. Labre in 1928

Actually an "Edison" outlet is what we commonly screw light bulbs into.  In the early days when there weren't many electrical gadgets, the power cords had an end that screwed into the sockets for "Edison" type lamps.  As mentioned, we didn't have pronged plugs with the associated sockets until Hubbell, and that took awhile to supplant the Edison lamp sockets.

Here's a modern LED upgrade for down lights. Note the "Edison" screw-in plug.

The ground pin is shaped like a U and that's how we refer to them.
Why do the Americans call it an Edison? Did he "invent" that as well?
Seems ironic as he was against AC power.
Maybe we should call them Teslas 

Because not too long after that stage in our consumer electrical distribution system's development, most americans were paying their power bills to an entity with "Edison" in it's name from the late 80's onward (1880's 
Southern California and NYC Metro are still served to this day with power companies with Edison in their name and I'm sure there are others.
So it's quite obvious to call that connection to the power co. an "edison connector"

In my brief time in Canada everyone called their electric bill "Hydro" so I guess they had come up with a different name for their connector as "hydro connector" should actually imply hose fittings

In Britain (which it turn out invented the plug and socket before Hubbell) it was common to plug things into ceiling lamps not only for convenience but originally lighting was billed separately to other power and was cheaper.

An E26 screw base to be exact.

Up in the tundra, we call edison plugs "U ground" plugs.
Sorry for the redundancy...should've flipped back a bit.

Maybe, maybe not. In North America and Japan, E26 (26 mm) is the standard Edison screw base. In Europe, it is E27 (27 mm).

You might screw an E26 lamp into an E27 socket, but not the other way 'round.

Fair point.  I was making an assumption that we were looking at a US product. 

I've always enjoyed that bases are measured in mm, but lamp diameter is in 1/8ths of an inch (par38, T8)
