A good part of my professional life last year was taken up working with Showtime and Method (among others) to get Showtime Interactive built while we were still creating the Windows Media Center Presentation Layer platform (Media Center Markup Language + .NET 2.0).

Thanks to our friends over in developer envangelism you can learn more about what it took to build this experience at http://www.microsoft.com/casestudies/casestudy.aspx?casestudyid=4000000490.
