The first installment of the series appeared in the January 2002 issue of Heavy Metal Magazine.  The most recent appeared in the September 2010 issue.  Heavy Metal began running Joe In The Future as a print series in 2001 after the initial episode appeared as 3-minute internet flash web animation and Heavy Metal editor Howard Jorofsky suggested Weisfeld allow the magazine to run additional episodes as a print and Weisfeld then followed with several additional Joe in the Future installments for Heavy Metal.  The nearly simultaneous appearance of Joe in the Future as both web-animation and print episodes makes the series an early example of web-initiated Transmedia storytelling.
