And who could stand a kitchen without a “BASS-O-MATIC” from Saturday Night Live?
How about a thread for fictional brand names that were adopted later by real companies. Let us begin with
“U.S. Robotics”
The plethora of good names from the Sims, I wont list them all.
Ubik.
U.S. Robotics And Mechanical Men.
Alas, 3Com bought them out. Darn it.
Hm. Blackrock Oil. (Transformers, comic)
Genom (Bubblegum Crisis/Crash/2040)
I remember Hungry Nomad tv dinners from Hot Shots 2. Wish I could remember the other products.
Conglomo: We Own You
(from Rocko’s Modern Life)
From The Simpsons: Lil’ Lisa Slurry
And the ubiquitous and somewhat distressing Playpen, our alternative televisual reality’s Playboy.
I once bought a printer cartridge from the Staples website. There is (or was, when I used it) a blank for “company”, so I put “Sys-U-Comp, Inc.” This had been a fictional company name used as an in-joke with my friends - names that told you nothing about the company at all. Along with Compusys, Dynadyne, DataSoft, etc…
I still get catalogs sent to “Sys-U-Comp” from them. I haven’t bought anything for years, you’d think they’d leve me alone!
[sub]…not a brand name, but…[/sub]
the Googleplex theatre chain in the Simpsons
There is a Family Mart convenience store chain in Japan, but in the Doraemon cartoon, you can often see signs with Mamily Fart printed on them.
Non-fiction: There is a concrete factory near my house with a big giant sign bearing the name of the company; “OOPS!”
Probably better than naming your company “Oh Shit!” but not by much.
The Aleph-Null-plex from Futurama beats that.
A-1, makers of fine Disentigration Pistols.
Of course, there’s always Vandelay Industries, purveyor of fine latex products . . . but since it is already a fictional company in the context of the fictional Seinfeld universe, I’m not sure if it would count.
There’s the Marathon car rental company shown in Planes, Trains and Automobiles. The name seems fitting, considering the fact that Neal Page (Steve Martin) had to run one to get back to the airport after he found out his car wasn’t there.
What? No mention of Binford Tools?
Zik-Zak, one of Network XXIII’s main sponsors and driving force in the develpoment of “blibverts”…
Daystrom Industries, who build the multitronic computers at the hearts of Federation starships…
Cyberdyne Systems, who developed Skynet, and later a successful line of “Terminator” infiltration units…(there is an office building in Dallas with a “Cyberdyne” sign on it…I’m worried…)
OmniConsumer Products, who brought you the ED-209 and RoboCop…
LexCorp, Wayne Industries, Ferris Aircraft, and S.T.A.R. Labs, all with offices in Gotham City, Metropolis, and elsewhere in the DC Comics universe…
By the way, I always thought Yoyodyne Propulsions Systems’ motto was “A Growing Excited Company!” - I had forgotten about “Where the Future Starts Tomorrow!”
Damn, I wanted to be the first one to say Cyberdyne. 
We already had Nails cigarettes, but nobody mentioned Chewlie’s Gum??? For shame!
WeSaySo Corporation from Dinosaurs
From The Simpsons:
ILG - “Selling your body’s chemicals after you die.”
And Li’l Sweetheart Cupcakes – a subsidiary of ILG.
And of course, Happy Fun Ball
Log.
(I haven’t seen it mentioned yet. Did I miss it? Sheesh, I feel old.)
