An underwriting spot is an announcement made on public broadcasting outlets, especially in the United States, in exchange for funding. These spots usually mention the name of the sponsor, and can resemble traditional advertising in commercial broadcasting. However, there are legal restrictions, such as a prohibition of making product claims, announcing prices, or providing an incentive to buy a product or service. In the U.S., these restrictions apply to all non-commercial educational stations, and even for non-sponsoring companies and products.
Critics argue[who?] that these spots are a corrupting influence, and introduce the same commercial biases into Public broadcasting as exist the corporate media.
Underwriters are defined as third parties that voluntarily contribute cash to partially or fully finance the production or acquisition of a program by a PBS station. Underwriters do not include investment or licensing partners or distribution entities providing cash for other purposes.
The block of time containing underwriter credits is called the "underwriting credit pod"; it can be no longer than 60 seconds, with no more than 15 seconds allocated per underwriter. If any underwriter is mentioned, then all must be acknowledged.
Underwriting credit pods must "mirror the production values of the program and flow smoothly with program content and other packaging elements."
Underwriting credit pods must appear at the end of the program and may appear at the beginning. In news and public affairs programs, underwriting credits must be included in both places. The end underwriting pod can be either before or after the program's production credits; if an underwriting pod is including in the beginning, it must start within the program's first three minutes and should be placed after the program's opening or tease (in order to separate national underwriting from local underwriting).
When PBS partially funds the production, the underwriting credit pod must end with "...from Viewers Like You. Thank you"; when funding is received from the Corporation for Public Broadcasting (CPB), they are credited with a voiceover ("This program was made possible by the Corporation for Public Broadcasting") and a "visual treatment" consisting of the CPB logo, the tag line "a private corporation funded by the American people" and the CPB's website ("cpb.org").
