Advertiser-funded programming (AFP) is a recent term applied to a break away from the modern model of television funding in place since the early 1960s. Since that time, programmes have normally been funded by a broadcaster and they re-couped the money through selling advertising space around the content. This has worked fine for decades, but new technological advances have forced broadcasters and advertisers to re-think their relationship.
The concept is as old as television itself; the term soap opera is derived from the fact that the original soap operas were in fact funded and produced by soap companies such as Procter & Gamble. Shows such as the Texaco Star Theater, which were among the earliest television programs, included the practice. It was not until the quiz show scandals of the late 1950s, when particularly aggressive advertisers began rigging game shows to produce a more entertaining product, that the practice fell on the wayside. By the time television became a worldwide phenomenon in the late 1950s and early 1960s, the original model had mostly been eschewed in favor of the modern model, which separates programming and advertising. (The fact that many of the early television broadcasters outside the United States were public broadcasters that restricted the use of advertising may have been a contributing factor to this.)
With the advent of digital recording devices, also known as personal video recorders (PVR's), viewers can choose to record episodes or entire series of their favourite shows and watch them in their own time. Not only does this skew the idea of 'primetime', (advertisers being charged a premium for buying spots around the most popular viewing times), but it means viewers can skip the ads altogether.
Advertiser-funded programming, largely a neologism, is a solution to this change and means the advertiser pays to integrate their message in the TV programme itself, rather than just buying advertising space around it. It includes product placement, sponsorship, naming rights and more recently the actual creation of whole shows from scratch. Many of these projects are enabled by a content partnership where the programming is co-funded by multiple stakeholders.
