Problem: Stone was born as Douglas Jackson Brooks on June 19, 1956 in Marietta, Georgia. His mother, who was also a country music singer, taught him how to play guitar when he was five. When he was seven years old, his mother placed him onstage to open for Loretta Lynn. His mother and father later divorced, and afterward, he moved to live with his father.

In December 1999, Stone was aboard an airplane which skidded off a snowy runway at O'Hare Airport in Chicago; there were no injuries. Stone began piloting ultra-light airplanes as a hobby in 1999 and 2000. In March 2000, he suffered a broken left ankle, cracked rib, concussion, and bruised kidney after crashing his plane in Robertson County, Tennessee, and was briefly hospitalized before he resumed touring. Stone later said that the accident made him decide to quit flying planes. After the September 11, 2001 attacks, rumors circulated that Stone had been on one of the hijacked planes; a spokeswoman for the singer confirmed that he was at home with his family that day. Stone signed to Audium Entertainment in 2002 and recorded The Long Way. This album included seven new songs and acoustic re-recordings of "More Love", "Born in the Dark", and "I'd Be Better Off". One of the original songs on it was "POW 369", which was later recorded by Darryl Worley. Stewart Mason thought that it was "not nearly as suffocatingly slick" as Stone's previous albums, but questioned its commercial success. His next album did not come out until 2005, when he signed to the independent label Lofton Creek Records, recording the album In a Different Light. The album included a cover of "Georgia on My Mind", which was the first single, and re-recordings of "In a Different Light" and "Why Didn't I Think of That". A second album for Lofton Creek, My Turn, followed in 2007. It was led off by the single "Nice Problem". William Ruhlmann praised this album for having "a timeless country feel", also saying that "Stone sings with as much fervor and sincerity as ever." Ken Tucker of Billboard wrote that "He sounds as good as ever and his music is still relevant". In 2013, Stone toured with Bryan White and Shenandoah as part of the "Reliving the 90s Tour". He also returned to acting, with roles in the films When the Storm God Rides and The Story of Bonnie and Clyde.

Question:
John Logie Baird FRSE (; 13 August 1888 - 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
Baird made many contributions to the field of electronic television after mechanical systems had taken a back seat. In 1939, he showed a system known today as hybrid colour using a cathode ray tube in front of which revolved a disc fitted with colour filters, a method taken up by CBS and RCA in the United States. As early as 1940, Baird had started work on a fully electronic system he called the "Telechrome". Early Telechrome devices used two electron guns aimed at either side of a phosphor plate. The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-colour image could be obtained. He also demonstrated the same system using monochrome signals to produce a 3D image (called "stereoscopic" at the time). In 1941, he patented and demonstrated this system of three-dimensional television at a definition of 500 lines. On 16 August 1944, he gave the world's first demonstration of a practical fully electronic colour television display. His 600-line colour system used triple interlacing, using six scans to build each picture. Similar concepts were common through the 1940s and 50s, differing primarily in the way they re-combined the colours generated by the three guns. One of them, the Geer tube, was similar to Baird's concept, but used small pyramids with the phosphors deposited on their outside faces, instead of Baird's 3D patterning on a flat surface. In 1943, the Hankey Committee was appointed to oversee the resumption of television broadcasts after the war. Baird persuaded them to make plans to adopt his proposed 1000-line Telechrome electronic colour system as the new post-war broadcast standard. The picture resolution on this system would have been comparable to today's HDTV (High Definition Television). The Hankey Committee's plan lost all momentum partly due to the challenges of postwar reconstruction. The monochrome 405-line standard remained in place until 1985 in some areas, and the 625-line system was introduced in 1964 and (PAL) colour in 1967. A demonstration of large screen three-dimensional television by the BBC was reported in March 2008, over 60 years after Baird's demonstration.
