Credit can not be given to one single person for the invention of television. Its development was fueled by many different inventors working on individual projects. Many of these inventors where not trying to produce a television at all but their achievements were applied by others to help make image transmission possible. One of the first major breakthroughs was made in 1884 by Paul Nipkow. The "electric telescope" that he created used rotating metal disks and had the ability to transmit images over an electric wire with 18 lines of resolution. In 1906 Boris Rosing would further the technology by combining it with the Audion vacuum tube, and a cathode ray tube to produce early methods of electronically scanning and reproducing images.

In 1925 American Charles Jenkins and John Baird from Scotland, each demonstrate the mechanical transmissions of images over wire circuits. Baird would become the first person to transmit moving silhouette images using a mechanical system based on Nipkow's disk, and Jenkins would receive the first television license from the Federal Radio Commission in 1928.

By 1929 another inventor Vladimir Zworykin uses his kinescope invention to demonstrate the first practical system for both the transmission and reception of images. John Baird opens up the first television studio but the quality of his transmissions were poor. Iowa State University began broadcasting television programs in 1933, there were only around 200 television sets though to exist in the world at this time. By 1937 CBS and the BBC would also begin broadcasting black and white programming. The demand for color sets was answered by Peter Goldmark in 1940.
