Traffic (broadcasting)

Traffic (broadcasting) 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 Traffic (broadcasting) rather than just read about it. In short: In broadcasting, traffic is the scheduling of program material, and in particular the advertisements, for the broadcast day. In a commercial radio or TV station there is a vital link between sales (of advertisement or commercial space) and traffic in keeping the information about commercial time availability.

Key takeaways

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

Reference excerpt

In broadcasting, traffic is the scheduling of program material, and in particular the advertisements, for the broadcast day. In a commercial radio or TV station there is a vital link between sales (of advertisement or commercial space) and traffic in keeping the information about commercial time availability. The station sales department sells airtime to its customers. It is not unusual in a single hour for 18–20 minutes to be commercials. The process begins with the programming department laying out a program schedule. Some programs are pre-recorded and air locally, some come from syndicators or networks. Some programs such as sports, news, and entertainment specials air live as they are happening. The traffic department schedules all of the programs and program elements and merges it into a traffic log. The traffic department receives orders from the sales department, who sells airtime to advertisers and places those commercials into available airtime slots called commercial breaks ("avails") at the best possible rates. The traffic department generates a daily log of programming elements programs, commercials, features and public service announcements. The log defines when they are scheduled to be aired. The log will be used by the on-air operator who actually plays the commercials. A copy of the log after the fact (sometimes called an AsRun Report) is used for reconciliation to determine what actually aired and then can be sent to accounting to bill the advertisers. Typically a broadcaster uses a broadcast management software system that allows for automation between departments. Some software systems are end-to-end and manage the whole spectrum of tasks required to broadcast a television or radio station, others specialize in specific areas, such as sales, programming, traffic, or automation for master control.

Process The traffic process starts by a salesperson making an agreement with a customer about a campaign. The agreement is called a sales order and it defines the dates when spots (advertisements) are run and the commercial terms of the campaign. The sales order usually also defines the product group in order to avoid conflicts in scheduling, for example, where two fast food vendors have a spot in the same break. At the station, a traffic person collects the sales orders and enters them into a computer system that will help to generate the daily logs. The traffic person also links the sales order with the possible media, such as an audio tape which contains the actual spot. When all the material is finished, the traffic system will be updated with parameters that define how the campaign will be run: in which dayparts there will be spots, how the spots are placed within a break, and what other separation criteria in addition to product groups there may be.

Worked examples

Example 1 — a first encounter with Traffic (broadcasting)

Start with the simplest possible case. Write down what Traffic (broadcasting) 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 Traffic (broadcasting) 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 Traffic (broadcasting) 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 Traffic (broadcasting)

In research: Traffic (broadcasting) 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 Traffic (broadcasting) 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: Traffic (broadcasting) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Broadcasting, Radio broadcasting, Television terminology, so understanding it makes those chapters shorter.
In everyday life: Look for Traffic (broadcasting) 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.
