t.v. ratings system

How was the rating industry started and how does entertainment-rating work? Since the beginning of radio and television, advertisers have been spending billions yearly in order to promote sales and gain business, so it just makes sense that they want to know if there advertising money is being put on the stations that are actually being listened to or watched. Because of this high demand of user information, companies began to come up with ways …

…it possible for the industries to come up with different programming for both television and radio that every spectrum of viewers or watchers will want to be a part of. Although it may not be cheap for the program networks or the radio industry to receive this type of audience and demographic information there will always be a need for it out there and there will also always be someone willing to pay for it.
