Tumblr blog network had 13 Million monthly unique visitors from around the world and 6 million from the US.

As it can be seen, most of the subdomains seem to be NSFW. This suggests that initially NSFW content was popular on Tumblr and that might have helped Tumblr in its growth. However, things changed after it went mainstream because we don’t see any top subdomains in 2012 that seem NSFW.
