The key demographic or target demographic is a term in commercial broadcasting that refers to the most desirable
demographic group to a given advertiser. Key demographics vary by outlet, time of day, and programming type, but they are generally composed of individuals who are younger and more affluent than the general public: "Young adult viewers have been TV's target demographic for decades, because they're thought to have less brand loyalty and more disposable income."[1] In the case of television, most key demographic groups consist of adults who are somewhere in age between 18 and 54.[2][3][4] For example, the key demographic for
reality television is women with
disposable income aged 18 to 34[5] whereas for
the WB Television Network it was "eighteen to thirty-four-year-old viewers."[6] Television programming is tailored to members of its key demographics:[7][8][9][10] "Despite the increase in time-shifting to watch recorded television and shows on the Internet, the use of television as an advertising vehicle is still determined by demographic characteristics or who is watching at what time."[11] The subset of ratings that only includes the key demographic of 18- to 49-year-olds is often referred to as the "key demo".[12] Certain
radio formats (especially those dubbed "classic") and television outlets may target persons 35 to 64, who generally have more
disposable income than
millennials, in part due to the
late 2000s recession, which impeded career opportunities for younger generations.[13]
