Tv production:

Production company refers to a company responsible for the development and physical production of performing arts, film, radio or a television program. The company may also be directly responsible for the raising of funding for the production or may do through an intermediary. The production company may be a small company, selling its product to a film studio or presenting it at a theatrical venue, or, in the case of film and television, it may be the studio itself.
A coproduction is a theatrical presentation or film made by more than one company. It is common for actors to form their own production companies so that they can have more control over their own careers
In its early stages of development, television included only those devices employing a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image. By the late 1920s, however, those employing only optical and electronic technologies were being explored. All modern television systems rely on the latter, however the knowledge gained from the work on mechanical-dependent systems was crucial in the development of fully electronic television.
The first time images were transmitted electrically were via early mechanical fax machines, including the pantelegraph. The concept of electrically-powered transmission of television images in motion, was first sketched in 1878 as the telephonoscope, shortly after the invention of the telephone. At the time, it was imagined by early science fiction authors, that someday that light could be transmitted over wires, as sounds were.[citation needed]
The idea of using scanning to transmit images was put to actual practical use in 1881 in the pantelegraph, through the use of a pendulum-based scanning mechanism. From this period forward, scanning in one form or another, has been used in nearly every image transmission technology to date, including television.
