lectromechanical television with motor-controlled scanners to capture images and an array of neon tubes to, collectively, form a display. On April 9, 1927, they presented the technology to the public across in a transmission between Washington D.C. and New York, a distance of more than 200 miles. Word of the demonstration reached England on April 28, the day after Baird's public offering had closed. Shareholders furiously claimed that Baird's had misled them, but he redeemed himself when he sent pictures by telephone line over a distance of 435 miles between London and Glasgow. Although the images flickered unsteadily, it was a major achievement. In 1928, Baird dispatched 30-line pictures between England and New York through an amateur short-wave radio station with a 35-foot antenna. The New York Times proclaimed, "Baird was the first to achieve television at all, over any distance. Now he must be credited with having been the first to disembody the human form optically and electrically, flash it piecemeal across the ocean and then reassemble it for American eyes. His success deserves to rank with Marconi's sending of the letter S." Video Communications: The Whole Picture In 1928, Baird demonstrated color television by transmitting images of blue flowers and red berries in a white basket. He used a transmitter with three interlaced spirals, one with a red filter, another with a green one, and a third with a blue filter. He thereby demonstrated the first transmission of a RGB (red, green, blue) component television signal. Next, Baird recorded video frequencies, noting the distinctive sound of a subject. He eventually filed a British patent for his "Phonovision." The device incorporated discs and played like a record to produce a recognizable picture-it foreshadowed the DVD. In 1928, Baird astonished the public by demonstrating a three-dimensional (3D) color television. On the receiving screen, two images were displayed that were separated by one-half an inch. One corresponded to objects as seen by the right eye,
