and excitement who doesn't enjoy a football game that is if you are one of the lucky ones who can get it can sit back in the comfort of their own home and enjoy every thrill of the game with no struggle for ticket out of the stadium the television cameramen are seeing to it that you can follow every detail of the game they're out there on the sidelines following every important piece of action people connect the cameras with the movie the units which are parked outside the stadium and from these trucks the scenes covered by the cameras are relayed to the main television nah let's see what a television studio looks like it's a mighty busy place when the broadcast is being made from the studio great banks of lights whittled down to plug the scenes cameramen wheeling in and out to pick up the action from the angles directed by the director to keep the action continuous while the costume those are changed and while different sets are being readied or to show an action which could not take place on a small stage productions of some broadcasts are made by projecting prepared motion picture film right into  television camera using the same actors and identical sets the motion pictures are made in advance the electrician the camera man the studio manager and the actors are all controlled by the director is job is to see that the broadcast proceed smoothly and without breaks because the picture on the television screen must be continuous camera run move in close on the g television and motion pictures are like because in both a series of still pictures is spliced rapidly before your eyes so rapidly that the memory of each picture lingers long enough so that it blends with the next picture and the object of the picture appears to move and now let's see what makes a picture a picture look closely at this one the closer still let's use a magnifying glass here that the picture is really made up of fountains of tiny dots arranged very close together but normally our eyes don't notice the dots especially when the pictures being moved this fact helps to make television and motion pictures possible television is simply a way of sending these dots from a transmitting station and putting them together to make a picture on the screen of a receiving set here is the way it works inside the television camera is a magical like trick i call the icon a scope one of the most important parts of which is this sensitive plate called a mosaic is a rectangular piece of mica covered with billions of tiny photoelectric cells arranged something like this the scenes being televised go through the camera lens and fall on the photo electric cells some of the cells receive lots of light others very little each cell according to how much light it gets builds up a corresponding electrical charge these charges collectively make up an electrical image on a mosaic these cells with their electrical charges are scanned by a stream of electrons the scanning beam skips every other line and returns to scan the remainder of the picture completing thirty pictures a second each picture is composed of five hundred twenty five individual scanning lines and electrical impulses released each time the stream covers a group of the photoelectric cells each separate impulse carried to another magic tube called the kinescope and are used to control another stream of electrons which bombard the face of the kinescope which is really the viewing screen when the beam strikes this fluorescent screen each electrical impulses change back into a spot of light in other words each spot of light picked up by the mosaic of tiny photoelectric cells in the television camera creates a corresponding spot of light on the receiving screen it moves back and forth so rapidly actually more than two and one half miles per second that a complete still picture is formed almost immediately the quick succession of thirty pictures a second produces the apparent motion that is why the pictures we see on the screen of our television receiver seem to move television has come of age here for instance is a reproduction of one of the first images received on a television screen compare that crude picture with these of today and you can judge for yourself how far along the road to perfection television has traveled it is bringing entertainment to millions and through its magic we are able to enjoy a combination of radio motion pictures and the stage actually some television patents were issued several years before the first automobile was built but because of many technical difficulties that had to be overcome its development was much slower just as the modern automobile is the result of years of research scientific engineering and testing by countless miles of actual use television is the result of endless experiments and new discoveries by patient scientists toiling in their laboratories it has been developed just does the easy writing qualities of today's automobiles were developed by progress through constant improvement today we sit back in roomy comfortably cushion seats in steel bodies insulated against heat and cool the noise surrounded by windows of crystal clear glass controlling the ventilation
