Reference excerpt

Halls is a British brand of a mentholated cough drop owned by Mondelēz International since 2015. In 2016, it was one of the biggest selling brands of over-the-counter medications sold in Great Britain, with sales of £32.5 million. Halls cough drops contain menthol, which acts as local anesthetic and creates a "cooling sensation". It also acts as a cough suppressant.

In warmer parts of the world, Halls is advertised as a mentholated hard candy and not a medicine for coughs.

Company history The Hall Brothers company was founded in 1893 by the brothers Edwin Franklin Hall, Thomas Harold Hall, and Norman Smith Hall. In 1902, Edwin left the partnership but Thomas and Norman remained. Initially in the business of jam manufacturing, the brothers eventually branched into boiled sweets and candies. The company first introduced Mentho-Lyptus, a sweet containing menthol and eucalyptus, in 1927 as a remedy for sore throats and cough suppressant. The cough drops were introduced to the United States in the 1950s. The Manchester-based company was acquired by Warner-Lambert in 1964. Production was moved to Dumers Lane, Radcliffe in 1970. Pfizer acquired Warner-Lambert for over $90 billion in 2000. In 2002, Pfizer announces to acquire Pharmacia, But because Pharmacia owns Luden's and Pfizer owned Halls, The FTC ruled that Pfizer can't legally own both Halls and Luden's as it will create a Duopoly in the cough drop market. As a result Pfizer sold Halls, along with Dentyne, Clorets, Certs, and Bubblicious to Cadbury Schweppes for $4.2 billion. Cadbury closed the Radcliffe factory at the end of 2004, as part of an effort to cut 10% of its global workforce, affecting 450 employees. By 2008, Halls accounted for one-third of Cadbury's candy revenues. Kraft Foods bought Cadbury for $19 billion in 2010. When Kraft split into two entities in 2012, Halls remained under Mondelez. In 2022, Mondelez announced its plan to divest the company's gum assets, along with Halls and other non-core brands, in order to focus more on its cookie business. The gum brands were sold to Perfetti Van Melle in 2023, while Halls remains up for sale.

Worked examples

Example 1 — a first encounter with Halls (cough drop)

Start with the simplest possible case. Write down what Halls (cough drop) 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 Halls (cough drop) 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 Halls (cough drop) 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 Halls (cough drop)

In research: Halls (cough drop) 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 Halls (cough drop) 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: Halls (cough drop) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name confectionery, Cadbury Adams brands, Mondelez International brands, so understanding it makes those chapters shorter.
In everyday life: Look for Halls (cough drop) 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.
