3H Productions (originally 3H Enterprises) held BotCon from 1997 to 2002.
The company was founded by Jon and Karl Hartman and Glen Hallit prior to BotCon 1997 to help fund the convention.
At BotCon 2002, it was announced that 3H had secured the official Transformers convention license, as well as licenses to produce comic books and start a fan club.
Since the Hartmans owned the BotCon name, 3H's 2003 and 2004 conventions were called "The Official Transformers Collectors Convention," or OTFCC for short.
