Video technology was one of the main technologies, initially created for mechanical television systems. Subsequently, the presence of Cathode Ray Tube (CRT) television systems emerged to substitute the mechanical television systems; however, various emerging technologies used to support video display devices started to appear. Then, a research team led by Charles Ginsburge commenced its research work to develop one of the first video device, so-called practical Video Tape Recorder (VTR). In 1951, live images from television camera were captured by the first video tape recorder through the process, which camera electrical impulses were converted while the information onto magnetic video tape was saved simultaneously.
