Cross-promotion is a form of marketing promotion where customers of one product or service are targeted with promotion of a related product. A typical example is cross-media marketing of a brand, for example Oprah Winfrey's promotion on her television show of her books, magazines and website. Cross-promotion may involve two or more companies working together in promoting a service or product, in a way that benefits both. For example, a mobile phone network may work together with a popular music artist and package some of their songs as exclusive ringtones; promoting these ringtones can benefit both the network and the artist. Some major corporations, for example Burger King, have a long history of cross-promotion with a range of partners (see Burger King advertising). The Disney Channel has also made extensive use of cross-promotion.Movie tie-ins are good examples of cross-promotion. On occasion, badly planned cross-promotions can backfire spectacularly such as 1992 Hoover free flights promotion fiasco.
Co-marketing and co-branding are particular forms of cross-promotion.
A 2001 study by the Project for Excellence in Journalism found that US media outlets tend to cover their own company's goods and services much more frequently than others but declare the link only 15% of the time. For example, CBS was nearly twice as likely to carry Viacom products as ABC and NBC combined.
In Flat Earth News (2009), Nick Davies wrote that both Tiny Rowland and Robert Maxwell had regularly interfered with their respective UK newspapers to support their business interests. The UK's Private Eye has a regular "I Sky" column highlighting cross-promotion by News Corporation's UK newspapers (The Sun and The Times), focusing on references to the Corporation's Sky television network.
