Paul Colligan posted some interesting podcasting stats reported at the Corporate Podcasting Summit in London that he’s mentioned he’s attending about 1000 times the past two weeks (I kid because I care Paul). Interesting stuff:

• In 2006, 22% of their sample had heard of podcasting, and that rose to 37% in 2007
• Listenership rose only slightly between 2006 and 2007. As Paul noted, “just because they’re heard of Podcasting, doesn’t mean they’re doing anything about it.” Good point.
• Listener demographics are much more balanced in terms of age and gender than the conventional wisdom suggests. That’s very good news, and the word needs to get out on that.
