Rating is the audience of a particular program or station at a specific period of time expressed as a percent of the audience population. The percent sign is not shown, and the rating may represent household viewing or a specific demographic audience segment's listening or viewing.
Share is the audience of a particular television program or time period expressed as a percent of the population viewing TV at that particular time. Share, then, is a percent allocation of the viewing audience and differs from the rating which is a percent of the potential audience. Share is usually reported on a household basis.
HUT (homes using television) at a particular time, is expressed as a percent of all TV homes and PUT (persons using television) at a particular time, is expressed as a percent of all persons in TV homes. PUT combines all persons viewing, rather than reporting specific program viewing.
