Dear Steven,Enjoyed hearing from you and learning of your interest in puppetry. The Henson Company definitely is the major group creating today's puppet video. There is a magic in puppetry that resides somewhere between animated cartoons and real people. My advice would be that you create the most interesting characters you can, write the best script your imagination can conjure, and videotape a 5 minute segment that makes the viewer want to see more. This will be your demo tape, an absolute necessity to getting media companies interested in your work. Then offer to send it to anyone connected to children's entertainment. By all means get feedback from people who are in the entertainment business themselves.
Best wishes for your success,
Here's What He Looks Like!
