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."
 In the case of television, most key demographic groups consist of adults who are somewhere in age between 18 and 54.
 For example, the key demographic for reality television is women with disposable income aged 18 to 34 whereas for the WB Television Network it is "eighteen- to thirty-four-year-old, , viewers" Television programming is tailored to members of its key demographics: "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."
 The subset of ratings that only includes the key demographic of 18- to 49-year-olds is often referred to as the "key demo".
 Certain radio formats (especially those dubbed "classic") and television outlets may target persons 35 to 64, especially since the late 2000s recession wiped out many career opportunities for millennials, since the 35–64 demographic has much more disposable income.

Nakayoshi (なかよし , "good friends") is a monthly "shōjo" manga magazine published by Kodansha in Japan.
 First published in December 1954, it is a long-running magazine with over 60 years of manga publication history.
 The target demographic for "Nakayoshi" (like "Ribon" and "Ciao") is girls of age 8–14.
 Roughly the size of a phone book (hence the term "phone book manga"), it generally comes with "furoku", or small gifts, such as popout figures, games, small bags, posters, stickers, and so on.
 The "furoku" is an attempt to encourage girls to buy their own copies of the magazine rather than just share with a friend.
 In the mid-1990s, Nakayoshi retailed for 400 yen and had an average of 448 pages.
 The estimated circulation of Nakayoshi at this time was 1,800,000.

Shōjo, shojo, or shoujo manga (少女漫画 , shōjo manga ) is manga aimed at a teenage female readership.
 The name romanizes the Japanese 少女 (shōjo), literally "young woman".
 Shōjo manga covers many subjects in a variety of narrative styles, from historical drama to science fiction, often with a focus on romantic relationships or emotions.
