Must-carry

Must-carry is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Must-carry rather than just read about it. In short: In cable television, many governments, including the ones of the United Kingdom, the United States, and Canada, apply a must-carry regulation stating that forces a cable TV provider to carry the public interest programming, like locally licensed television stations, on a provider's system. In some countries, this "traditional" approach had been extended to the Internet information sources.

Key takeaways

  • Must-carry belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Must-carry to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Must-carry from memory before moving on to harder problems.

Reference excerpt

In cable television, many governments, including the ones of the United Kingdom, the United States, and Canada, apply a must-carry regulation stating that forces a cable TV provider to carry the public interest programming, like locally licensed television stations, on a provider's system. In some countries, this "traditional" approach had been extended to the Internet information sources. Similar approach in other sectors, like telecommunications, is called universal service.

Canada

Under current Canadian Radio-television and Telecommunications Commission (CRTC) regulations, the lowest tier of service on all Canadian television providers may not be priced higher than $25 a month, and must include all local Canadian broadcast television channels, local legislative and educational services, and all specialty services that have 9.1(1)(h) must-carry status. All specialty channels licensed by the CRTC as a mainstream news channel must also be offered by all television providers, although they need not be on the lowest tier of service. In the mid-to-late 1970s, the CRTC implemented a rule that a cable system must carry a broadcast television station at no cost to the broadcaster if the transmitter emitted an equivalent isotropically radiated power (EIRP) of at least 5 watts. This CRTC rule may have changed over the years, but in principle, a broadcast television station transmitting at 1 kilowatt EIRP must be carried. The status of terrestrial digital only channels with respect to the must-carry requirement is untested, because, unlike those in the U.S., some television stations in Canada did not operate digital signals until the digital television transition in Canada in August 2011. The digital broadcasters that were active before then were merely high-definition simulcasts of those stations' existing analog signals in major centres, such as Toronto and Vancouver, with no additional digital subchannels offered. This was because broadcasters declined to carry subchannels, for which CRTC rules required separate licenses. For many years, the Canadian must-carry rules created very little friction between terrestrial broadcasters and cable systems, as providers are allowed to more aggressively implement other digital telecommunications services (like cable internet services and IP telephony) with less overall regulation than their U.S. counterparts. However, in 2008, two of Canada's largest commercial television networks, CTV and Global, began to demand that the CRTC permit them to charge a fee for cable carriage. CBC Television and A-Channel joined the campaign in 2009, alleging that some smaller-market stations would be forced to cease operations if this was not allowed. The CRTC initially rejected these demands, but later re-opened discussion with Canadian broadcasters to allow charging carriage fees. In 2012, a 5–4 decision by the Supreme Court of Canada ultimately ruled the CRTC did not have the authority to permit broadcasters to charge carriage fees from cable and satellite providers.

United States In the United States, the Federal Communications Commission (FCC) regulates this area of business and public policy pursuant to 47 U.S.C. Part II. These rules were upheld in a 5–4 decision by the Supreme Court of the United States in 1994 in the case Turner Broadcasting v. FCC (95-992). Although cable television service providers routinely carried local affiliates of the major broadcast networks, independent stations and affiliates of minor networks were sometimes not carried, on the premise it would allow cable providers to instead carry non-local programming which they believed would attract more customers to their service. Many cable operators were also equity owners in these cable channels, especially Tele-Communications Inc., then the nation's largest multiple system operator (MSO), and had moved to replace local channels with equity-owned programming (at the time, TCI held a large stake in Discovery Communications). This pressure was especially strong on cable systems with limited bandwidth for channels. The smaller local broadcasters argued that by hampering their access to this increasing segment of the local television audience, this posed a threat to the viability of free-to-view broadcast television, which they argued was a worthy public good. Local broadcast stations also argued cable systems were attempting to serve as a "gatekeeper" in competing unfairly for advertising revenue. Some affiliates of major networks also feared that non-local affiliates might negotiate to provide television programming to local cable services to expand their advertising market, taking away this audience from local stations, with similar adverse impact on free broadcast television. Although cable providers argued that such regulation would impose an undue burden on their flexibility in selecting which services would be most appealing to their customers, the current "must-carry" rules were enacted by the United States Congress in 1992 (via the Cable Television Protection and Competition Act), and the U.S. Supreme Court upheld the rules in rejecting the arguments of the cable industry and programmers in the majority decision authored by Justice Anthony Kennedy. That decision also held that MSOs were functioning as a vertically integrated monopoly. A side effect of the must-carry rules is that a broadcast station cannot charge a cable television provider license fees for the program content retransmitted on the cable network under the rule. But note that must-carry is an option of the station and the station may, in lieu of must-carry, negotiate license fees as part of a retransmission consent agreement.

Applicability There are a few exceptions to must-carry, most notably:

Worked examples

Example 1 — a first encounter with Must-carry

Start with the simplest possible case. Write down what Must-carry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Must-carry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Must-carry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Must-carry

In research
Must-carry appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Must-carry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Must-carry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Broadcast law, Cable television in Canada, Cable television in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Must-carry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
