1. percentage of households in a specific geographic area with television sets tuned to a particular program as compared to the percentage of households with television sets turned on (HUT- see Households Using Television). In an area where only 10 television sets are turned on and 5 are tuned to a particular program, the program would have a share of 50. However, a program share of 50 means nothing without knowing the possible size of the audience. The program rating will tell this information. If there are 100 television households in this same geographic area, the rating for this particular program would be 0.5, indicating that 5 out of a possible 100 households have their sets tuned in to the program. Advertisers need to know both the program share and rating in order to determine the most effective placement of their commercials. Therefore, share and rating are key concepts in understanding the planning of broadcast media for advertising.
