Problem: 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.

did he face any other challenges?

Problem: Phillips was born in Albany, Georgia, to Sheryl (Jacks) and Phillip LaDon "Donnie" Phillips, Sr., and moved to Leesburg, Georgia when he was 12. He has two older sisters, LaDonna, the eldest, and Lacey. Phillips grew up in Sasser and Leesburg, and attended Lee County High School. He graduated from Albany Technical College with a major in Industrial Systems Technology, but missed the graduation ceremony due to his obligations to American Idol.

Phillips auditioned in Savannah, Georgia. He sang "Superstition" by Stevie Wonder. The judges then asked him to perform a second song with his guitar, and he performed Michael Jackson's "Thriller." He advanced to the Hollywood rounds, and later to the Las Vegas round. On February 23, 2012, Phillips was chosen as one of the Top 25 semi-finalists, and was then voted into the Top 13.  His performance style on the show has been compared to Dave Matthews, and he covered one of his songs, "The Stone," in the competition. When asked about Phillips' imitation of his style, Dave Matthews said: "More power to him, I don't mind," and added "He should kick my ass, [then] maybe I can retire and he can take over my band." Mentor Stevie Nicks said Phillips would have been good enough to join Fleetwood Mac back in 1975, after his performance of Jonny Lang's Still Rainin, which he received a standing ovation from the judges.  After the Top 13 performance night, Phillips was taken to a doctor for possible kidney stones. He had eight procedures while he was on Idol, and considered quitting the show due to the pain.  For his Top 3 performance, Phillips sang Bob Seger's "We've Got Tonight." For Top 4, he did a cover of Damien Rice's Volcano - which has been heralded as one of the best American Idol performances of all time. As the sole contestant who was never in jeopardy of elimination in any week of the competition, Phillips became the winner on the finale against Jessica Sanchez after a record-breaking 132 million votes were cast. His coronation song, "Home," was released after his performance, and had the biggest digital sales week for any Idol winner's coronation song.  ^Note 1 Due to the judges using their one save on Jessica Sanchez, the Top 7 remained intact for another week.

Has he released any albums?

Problem: Robert Lee "Bullet Bob" Hayes (December 20, 1942 - September 18, 2002) was an Olympic sprinter turned American football wide receiver in the National Football League for the Dallas Cowboys. An American track and field athlete, he was a two-sport stand-out in college in both track and football at Florida A&M University. He has one of the top 100 meter times by NFL players. Hayes was enshrined in the Dallas Cowboys Ring of Honor in 2001 and was selected for induction in the Pro Football Hall of Fame in January 2009.

Hayes was a highly recruited athlete, and accepted a football scholarship from Florida A&M University a historically black college, where he excelled in track & field.  He never lost a race in the 100 yard or 100 meter competitions, but mainstream schools of the area still did not invite him to their sanctioned meets. In 1962 the University of Miami invited him to a meet on their campus, where he tied the world record of 9.2 seconds in the 100-yard dash, which had been set by Frank Budd of Villanova University the previous year. He also was the first person to break six seconds in the 60 yard dash with his indoor world record of 5.9 seconds.  In 1963, although he never used a traditional sprinter form, he broke the 100-yard dash record with a time of 9.1, a mark that would not be broken for eleven years (until Ivory Crockett ran a 9.0 in 1974). That same year, Hayes set the world best for 200 meters (20.5 seconds, although the time was never ratified) and ran the 220 yard dash in a time of 20.6 seconds (while running into an eight mph wind). He was selected to represent the United States in the 1964 Summer Olympics in Tokyo. His football coach Jake Gaither was not very high on giving Hayes time to train, which caused then president Lyndon B. Johnson to call him in order to allow Hayes time off and to keep him healthy.  He was the AAU 100 yard dash champion three years running, from 1962-1964, and in 1964 was the NCAA champion in the 200 meter dash. He missed part of his senior year because of his Olympic bid for the Gold medal.  In 1976, he was inducted into the inaugural class of the Florida A&M University Sports Hall of Fame. In 1996, he was inducted into the Southern Intercollegiate Athletic Conference Hall of Fame. In 2011, he was inducted into the Black College Football Hall of Fame.

When did his college career end?
