[co-author: Davina Sashkin] In an unusual move, the Federal Communications Commission (FCC or Commission) Enforcement Bureau released an Enforcement Advisory to remind broadcasters of their sponsorship identification obligations. The same day, the Media Bureau issued a reminder to commercial broadcasters of the requirement to upload time brokerage agreements (TBAs), joint sales agreements (JSAs) and shared services agreements (SSAs) to their online public inspection files (OPIFs). Sponsorship Identification Under the Communications Act of 1934, as amended (the Act), and the Commission’s sponsorship identification rules (collectively, the Sponsorship ID Laws), broadcasters are required to air disclosures for programming that is paid for or furnished by a third party. The Sponsorship ID Laws derive from the principle that listeners and viewers are entitled to know who might be seeking to persuade them and are designed to help audiences distinguish third-party content from station editorial content. Broadcasters can surmise that the FCC felt it appropriate to remind licensees of the requirements in the aftermath of the Commission’s assessment of a $233,000 forfeiture against Cumulus Radio for airing third-party content without the necessary sponsorship identifications, in violation of the law, FCC policy and Cumulus’ prior consent decree with the Commission.
