In 1969, the Children's Television Workshop produced an unaired test pilot for Sesame Street shown only to a focus group of children. After incorporating the data gathered by the test pilot and other sources, the first ever episode of Sesame Street (Episode 0001) debuted. The actor who played Gordon in Episode 0001 was Matt Robinson, who held the role through season 3. In seasons four and five, Hal Miller took over; and since season six, Roscoe Orman has played the role. However the actor who played Gordon in the test pilot was uncredited and originally unknown (and awareness of his existence was first truly sparked following online posting and analysis of images from the test pilot).
