441-line is the number of scan lines in some early electronic monochrome analog television systems. Systems with this number of lines were used with 25 interlaced frames per second in France from 1937 to 1956,[1] Germany from 1939 to 1943,[2][3] Italy from 1939[1] to 1940, Japan in 1939,[4] as well as by RCA in the United States with 30 interlaced frames per second from 1938 to 1941. Broadcasts were planned in Finland for 1940,[1] but eventually cancelled due to World War II. Some experiments with a similar system were carried out on the USSR in the 1930s.[1]
