we have a studio, a workshop, of ralph baird, who actually invented pong, which was the first interactive tv program. and look today how many interactive programs there are. through this, you can learn about how you preserve your intellectual rights through patents, and you can learn about how technology started in one place, and then grew, and grew. -- grew and grew in america. what i love most is this sweater. he was a real human being who escaped from germany, came and found himself as one of the great inventors of all kinds of things in his america. what we are trying to do here is explain how america, and actually the world, has seen innovation and invention and how it has been captured from the start of this country into today and continues to be a major component of how we think, live, and act. now you really get the excited , privilege of listening to curators about individual objects. it is the kind of experience you will have when you visit this wonderful wing of innovation. kathleen: i am the business history curator at the national museum of american history at the smithsonian
