Some classified magazines specialise in particular areas, for example the sale of cars.
Such magazines may be national or local; distribution is via kiosks, newsstands, or dump bins, and less often via free home delivery or paid-for subscription through the mail.
The decision as to which business model to pursue rests largely on the perceived value of the advertisements to the readers, and the perceived value to the advertisers of receiving responses to their ads.
As well as publishing the personal ads, the publishers of contact magazines often run an anonymous mail forwarding service that allows advertisers to identify themselves only with box numbers.
Specialized magazines also existed for those with specific sexual preferences, such as those seeking BDSM encounters, or the services of professional dominants or submissives.
