Dates for comments and replies on the FCC's Notice of Proposed Rulemaking to implement the CALM Act, regulating the volume levels of commercials, have now been set. We provided a detailed summary of that NPRM here. As set out in that summary, the NPRM asks many questions of broadcasters, cable companies, and other Multichannel Video Programming Distributors about implementation of the CALM Act, including who must comply, how compliance can be achieved, and the impact of reliance on program suppliers (networks, broadcast programming carried on cable, etc.) on compliance.
