Advertising media selection is the process of choosing the most efficient media for an advertising campaign. To evaluate media efficiency, planners consider a range of factors including: the required coverage and number of exposures in a target audience; the relative cost of the media advertising and the media environment. Media planning may also involve buying media space. Media planners require an intricate understanding of the strengths and weaknesses of each of the main media options. The media industry is dynamic - new advertising media options are constantly emerging. Digital and social media are changing the way that consumers use media and are also having an impact on how consumers acquire product information.
The selection of advertising media for a given campaign requires a deep and rich understanding of the media options available.
Television advertising offers the benefit of reaching large numbers in a single exposure. Yet because it is a mass medium capable of being seen by nearly anyone, television lacks the ability to deliver an advertisement to highly targeted customers compared to other media outlets. Television networks are attempting to improve their targeting efforts. In particular, networks operating in the pay-to-access arena, such as those with channels on cable and satellite television, are introducing more narrowly themed programming (i.e., TV shows geared to specific interest groups) designed to appeal to selective audiences. However, television remains an option that is best for products that targeted to a broad market. The geographic scope of television advertising may vary, from local or regional advertising through to national coverage, depending on whether public broadcasting or subscriber-based cable services are used.
Television advertising, once seen as the mainstay of media advertising, is facing numerous challenges from alternative media, especially interactive and social media. Technological innovations, especially the advent of ad blocking and zapping, has eroded TV's immediacy and relevance for some audiences.
Promotion through radio has been a viable advertising option for over 80 years. Radio advertising is mostly local to the broadcast range of a radio station, however, at least three options exist that offer national and potentially international coverage. First, in many countries there are radio networks that use many geographically distinct stations to broadcast simultaneously. In the United States such networks as Disney (children’s programming) and ESPN (sports programming) broadcast nationally either through a group of company-owned stations or through a syndication arrangement (i.e., business agreement) with partner stations. Second, within the last few years the emergence of radio programming delivered via satellite has become an option for national advertising. Finally, the potential for national and international advertising may become more attractive as radio stations allow their signals to be broadcast over the Internet.
