The year was 1978. With a blockbuster Superman movie on the horizon, DC Comics editor Julie Schwarz said that he didn’t plan on changing anything in the Superman comics to tie in with the movie, because a) the books were already selling well, and b) the movie would bring in new readers.
Neither of those statements turned out to be true.
In reality, the sales of both Action Comics and Superman had been falling precipitously for over a decade. Between 1965 and 1975, Action Comics lost 56% of its sales — 525,000 copies a month to 231,000 — and Superman lost 64%, going from a healthy 824,000 copies a month to an anemic 296,000 in ten years.
In 1979, when Superman: The Movie was by far the #1 box office draw in the country, Action Comics sales actually dropped, from 184,000 in 1978 to 161,000 in 1979, and they kept on going down. Superman sales went up a little bit, from 223,000 to 246,000, but then they dropped all the way to 179,000 in 1980.
It’s now an accepted fact that successful superhero movies encourage people to watch more superhero movies, but they don’t do much for comics sales. Today, we’re going to take a look at a 1978 issue of Action Comics, and see if we can figure out why.
