From Co.Create's excellent article about the controversy over the Watchmen prequels, Alan Moore explains everything to you:
There's been a growing dissatisfaction and distrust with the conventional publishing industry, in that you tend to have a lot of formerly reputable imprints now owned by big conglomerates. As a result, there's a growing number of professional writers now going to small presses, self-publishing, or trying other kinds of [distribution] strategies. The same is true of music and cinema. It seems that every movie is a remake of something that was better when it was first released in a foreign language, as a 1960s TV show, or even as a comic book. Now you've got theme park rides as the source material of movies. The only things left are breakfast cereal mascots. In our lifetime, we will see Johnny Depp playing Captain Crunch.
