TVRs (Television Viewer Ratings) are the
standard buying currency for television advertising in the UK. Television
ratings are expressed as a percentage of the potential TV audience viewing at
any given time. It Measures the popularity of a program or advert by comparing
the number of target audience viewers who watched against the total available
as a whole. One TVR is equivalent to 1% of a target audience. If an ad in any
afternoon show gets a Housewives TVR of 20, that means that 20% of all
Housewives viewed the ad. TVR=Reach x Time Spent
