RTÉ Guide

RTÉ Guide 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 RTÉ Guide rather than just read about it. In short: The RTÉ Guide is a television and radio listings magazine in Ireland published by RTÉ Commercial Enterprises Ltd, a subsidiary of Raidió Teilifís Éireann (RTÉ). The magazine offers detailed programme listings for RTÉ channels, as well as Virgin Media One, TG4, Virgin Media Two, BBC One, BBC Two, UTV, and Channel 4, as well as less detailed listings for variations of BBC Wales, ITV Wales, S4C and a number of satellit…

Key takeaways

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

Reference excerpt

The RTÉ Guide is a television and radio listings magazine in Ireland published by RTÉ Commercial Enterprises Ltd, a subsidiary of Raidió Teilifís Éireann (RTÉ). The magazine offers detailed programme listings for RTÉ channels, as well as Virgin Media One, TG4, Virgin Media Two, BBC One, BBC Two, UTV, and Channel 4, as well as less detailed listings for variations of BBC Wales, ITV Wales, S4C and a number of satellite and cable channels. RTÉ Radio programme listings are also published. Lifestyle and celebrity articles are also included in the magazine.

History and profile The RTÉ Guide began publication on 1 December 1961 as the RTV Guide and changed its name to the current name on 8 July 1966. Initially, listings were carried for Radio Luxembourg, AFN and BBC Northern Ireland but these were later dropped after a few years and only RTÉ programme listings were carried. From 8 January 1977, the RTÉ Guide switched from tabloid format to a compact magazine size and also changed from monochrome into colour. After United Kingdom listings magazines such as Radio Times and TV Times were deregulated from 1 March 1991, the magazine began carrying BBC, UTV/HTV Wales and Channel 4/S4C listings from 13 April of that year, as well as three more services include Teilifís na Gaeilge (31 October 1996), Channel 5 (30 March 1997) and TV3 (20 September 1998) were also added. A special Christmas double issue of RTÉ Guide is published every year to cover the Christmas and New Year period since 1970. In April 2018, the design of the RTÉ Guide was changed for the first time in a number of years. On 19 May 2019, it was reported that RTÉ was considering selling the RTÉ Guide. On 16 June 2019, it was reported that the Sunday Business Post owner, Enda O’Coineen, might acquire the RTÉ Guide. However by 5 December 2019, RTÉ had abandoned the proposed sale. Selected articles and photos used in the magazine went online in 2025 via RTÉ Libraries and Archives.

Circulation The Audit Bureau of Circulations circulation figures for the RTÉ Guide were:

Figures subsequent to 2018 are not available because the RTÉ Guide is no longer registered with the Audit Bureau of Circulations.

Worked examples

Example 1 — a first encounter with RTÉ Guide

Start with the simplest possible case. Write down what RTÉ Guide 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 RTÉ Guide 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 RTÉ Guide 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 RTÉ Guide

In research: RTÉ Guide 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 RTÉ Guide 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: RTÉ Guide is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s in Irish music, 1961 establishments in Ireland, 1970s in Irish music, so understanding it makes those chapters shorter.
In everyday life: Look for RTÉ Guide 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.
