Stands for Diffusion, Information, and Communication. An animation company that brought us Inspector Gadget, Sonic The Hedgehog, translated (and apparently badly if that's possible)that Sailor Moon crap from Japan, and, infamously, made M.C. Hammer's own short-lived cartoon "Hammerman".
Their end logo is well-known: the kid in bed with the bedroom window open, in which the camera zooms out of as a star swirls around dotting the I in DIC, and an unseen kid says "DIC" as that happens. Weird idea to feature a kid in bed in my opinion.
DIC is not pronounced "dick", although that would be funny!
A line from Led Zeppelin's "Stairway To Heaven", and since no one really knows what that song means, no one really knows what "all that glitters is gold" means either.
