[DC/Marvel] Why are DC comics set in fictional cities like Gotham and Metropolis while Marvel comics are set in real places like New York?

I **know** that not all places in Marvel are real. (like wakanda and Dr. Doom's contry) but i'm talking about the earlier comic heroes like Batman and Superman, who protect and serve fictional cities like gotham and Metropolis, while the X-men/Spiderman/fantastic four and avengers do it in real-life cities?

**EDIT:** Well, this has blown up. at least someone actually answered my question. thanks everyone.

It was a marketing decision. When Marvel was making it's move, DC was silly and unrealistic, with dream stories and imaginary stories. Stan Lee decided that his heroes would operate in the "real" world, have "real" problems and be more open (less secret identities, no Jimmy Olsens, etc.). And it worked. People were engaged in the stories and Marvel grew.
