With the acquisition of Club Penquin last year, the Walt Disney Company is making a significant entrance into social media.  This morning at the opening session of the McGraw Hill Media Summit, Robert Iger, President and CEO of Disney spoke of Penguin Club and his igloo, a location he has staked out in the virtual world for kids.

He announced that the company would be building other social networking sites around its properties.

More from the conference to come.
