The Media Rating Council (MRC) issued a draft version of its Digital Audio Measurement Guidelines for a 45-day public comment period. The draft was developed in collaboration with a large working group of organizations involved in the digital audio industry, which included digital audio ad buyers and sellers, digital audio content distributors, measurement services, and others. Also integrally involved in the project as participating industry associations are the Radio Advertising Bureau (RAB), the National Association of Broadcasters’ Committee on Local Radio Audience Measurement (COLRAM), the Interactive Advertising Bureau (IAB), and the IAB Tech Lab.
