Comic Books and Graphic Novels
Graphic novels and comic books based on Philip K. Dick novels/stories have been closely associated with movies until 2009, when the comic books format started to be exploited more broadly. The first PKD comic books were Blade Runner published by Marvel Comics in the wake of the release of the movie in 1982.
We'll have to wait 24 years, until 2006 when the movie A Scanner Darkly was released, to see a graphic novel (no comic books here) being made based on the screenplay by David Linklater. Not a surprise since the movie was an animated movie (shot with real actors and turned into an animated movie in postproduction).
In 2009 we saw the launch of the Do Androids Dream of Electric Sheep (DADOES) comic book series by Boom! Studios. The 22 issues series, published between 2009 and 2011, uses the exact text of the book. This series was followed/paralleled by a second series Do Androids Dream of Electric Sheep. Dust to Dust., which is a prequel of the first series. This time the story, as well as the text, are not from Philip K. Dick but inspired from the DADOES. These two series were published with several covers for each issues.
In 2010 Marvel Comics returned to PKD with a 5-issues series of Philp K. Dick Electric Ants, based on the short story of the same title.
