If you wonder which of the 267 APIs on this site people view most often you might be surprised. It's not Google Maps, it's YouTube. Which has been true for quite some time. But the number of mashups using YouTube has been small, until recently when they've started to pick-up.
Music video content provider MTV recently announced that its Content API is out of private beta and available to the general public. Available as part of a new MTV Networks Developers Tools web site, the RESTful API gives access to content from MTV, VH1, CMT and Logo. The API supports a variety of open standards including OpenSearch and MediaRSS for data results (see our new MTV API profile for more details).
