GriffTech was a company in Hill Valley in 2032, which was founded by Griff Tannen. It was the developer of the popular social media network ThingMeme, which allowed inanimate objects to post selfies on the internet. ThingMeme was created with financing secured from Douglas J. Needles on June 13, 2032.
ThingMeme originally inadvertently caused a nuclear holocaust in 2045 when Griff Tannen uploaded a virus that was meant to flash the word butthead on every object on Earth. The virus caused a short circuit in the Mr. Fusion network, creating an explosion in all one hundred million of the tiny nuclear reactors in the units.
