Line 56: The advancement of all-electronic television (including [[Video camera tube\|image dissector]]s and other camera tubes and [[cathode ray tube]]s for the reproducer) marked the beginning of the end for mechanical systems as the dominant form of television. Mechanical TV usually only produced small images. It was the main type of TV until the 1930s. All-electronic television, first demonstrated publicly by [[Philo Farnsworth]] in 1934, and first used for broadcasting in 1936, was quickly advancing past this point, reaching 400 to more than 600 lines with fast field scan rates in the next few decades. The last mechanical television broadcasts ended in 1939 at stations run by a handful of public universities in the United States. In 1939, [[Radio Corporation of America\|RCA]] paid Farnsworth $1 million for his patents after ten years of litigation, and RCA began demonstrating all-electronic television at the [[1939 World's Fair]] in [[New York City]]. == Color mechanical television ==
