People refer to this abrupt shrinking of the line as the "DC Implosion," mocking DC's marketing campaign that preceded it. To make matters worse, DC Publisher Jenette Kahn touted the expansion weeks before the axe started to fall. An effort to compete with Marvel Comics' growth resulted in a legendary failure, but some comic readers may be unaware about how and why this failure occurred and what the ramifications were.
There were cancelations in 1978 that had nothing to do with the DC Implosion. Freedom Fighters and Karate Kid made room for the DC Explosion. Many titles canceled in early and mid-1978 continued in Adventure Comics and other titles.
Without TV series supporting them, Welcome Back Kotter and Shazam! lay among the wreckage of 1978. Long-running titles Aquaman, Metal Men, Challengers of the Unknown, and Teen Titans finished their ongoing storylines. Finally, Steve Ditko's newest hero, The Odd Man, found his story moved into Detective Comics from the canceled Shade the Changing Man.
