Why were E.C. comics more popular than the other horror comics?

Have you found Ditko's 'The Thing' by Charlton, my gosh that was a great horror comic!

Yes! Great stuff indeed.

Can anyone name another comic (besides Classics Illustrated) that bragged about a writer on the cover of a comic, like EC did with Ray Bradbury? 

Of course, they only did that because Bradbury caught them ripping off a couple of his stories. But he was nice about it and EC immediately offered to make the relationship official.

Of course, they only did that because Bradbury caught them ripping off a couple of his stories. But he was nice about it and EC immediately offered to make the relationship official.

The fact that they thought of running a Ray Bradbury story (even without the credit), showed that Gaines and Feldstein were trying to bring out a quality product.  By the way, Bradbury sent them a friendly message about how nice it would be to recieve credit for his story, and EC quickly moved to make it official that they were adapting his stories.  How ever the realtionship between Bradbury and EC started, once it became official, EC used to boldly place on the cover, if they ran one of his stories.  Agian, what other horror (or sci-fi) comic of the period promoted that the issued contained a story by a known writer?
