What is Fee-for-carriage?

Legal Definition
Fee-for-carriage, value-for-signal, negotiation for value, or the "TV tax" all refer to a proposed Canadian television regulatory policy which would require cable and satellite television companies to compensate conventional, over-the-air television stations for the right to carry their local signals. Such a system has long existed in the United States, under the name of retransmission consent.

Various versions of the scheme are supported by most major conventional broadcasters, and all are opposed by virtually all cable, satellite, and IPTV (telephone company) service providers. These efforts have been promoted through a variety of means, including supporting ads on many conventional TV stations and their affiliated specialty channels, and opposing ads on local stations and during the local ad avails of U.S. cable channels (which are inserted by individual service providers).
