alt.toys.transformers, usually referred to by its initials ATT, is an outstandingly ancient Usenet newsgroup which was the de facto center of internet Transformers fandom in the 1990s. The group was created on September 11, 1993 to replace an awkward "mailing list" (really just a bunch of people manually sending email to a long list of recipients) that had started after Transformers nostalgia broke out in the newsgroup rec.arts.animation.
