Ratings

Commercial media relies heavily on “the ratings” – knowledge of how a programme or event is being viewed.  The data also gives an insight to the habits of viewers. Prices that the media can charge to advertise on their air is directly related to this.

It is vital therefore that broadcasters know how many people tune in at a specific time or to a specific show.

How a programme measures up is used to gauge the success or popularity of a particular broadcast.  Many networks use the data to boast about how they perform against their rivals.
