Futurama has a number of "sponsors" in the 30th century. Their commercials are sometimes shown as a cold opening, before the title credits.
(in order of appearance)
Glagnar's Human Rinds
Slogan: It's a buncha muncha cruncha humans!
Slogan: The fatal spore, with the funny name!
Slogan: Nobody doesn't like Molten Boron!
Slogan: The only teeth strong enough to eat other teeth!
There was also a deleted sponsor called "Soylent Chow" ("Because it's a dog-eat-dog dog world") with special voice, Scooby-Doo saying "It's really good!".
