http://BuildMyOnlineBiz.com - Tumblr is a social sharing platform, somewhat a cross between Facebook, Instagram, and PInterest. 90% of the posts seem to be related to pictures, and many contains links to an external blog. People can also post animated GIF/pictures (like 5 second movies), audio files, chat and blogs.
There are over 225 million accounts and some people build huge followings. It's a great site for fan clubs and teens. Any business might consider it as long as they are participating in other social sites.
Be aware that Tumblr allows Not Suitable For Work content, so you may get some surprises when viewing other peoples content.
