1965, the front cover was illustrated. Until the 1970s, colour was not used except on the cover. Since its first issue, New Scientist has written about the applications of science, through its coverage of technology. For example, the first issue included an article "Where next from Calder Hall?" on the future of nuclear power in the UK, a topic that it has covered throughout its history. In 1964, there was a regular "Science in British Industry" section with several items. Throughout most of its history, New Scientist has published cartoons as light relief and comment on the news, with contributions from regulars such as Mike Peyton and David Austin. The Grimbledon Down comic strip, by cartoonist Bill Tidy, appeared from 1970 to 1994. The Ariadne pages in New Scientist commented on the lighter side of science and technology and included contributions from David E. H. Jones, Daedalus. The fictitious inventor devised plausible but impractical and humorous inventions, often developed by the (fictitious) DREADCO corporation. Daedalus later moved to Nature. Issues of (The) New Scientist from issue 1 to the end of 1989 are free to read online; subsequent issues require a subscription. In the first half of 2013, the international circulation of New Scientist averaged 125,172. While this was a 4.3% reduction on the previous year's figure, it was a much smaller reduction in circulation than many mainstream magazines of similar or greater circulation. UK circulation fell by 3.2% in 2014, but stronger international sales increased the circulation to 129,585. A monthly Dutch edition of New Scientist was launched in June 2015. It replaced the former (NWT) magazine, adopting its staff and subscribers. The editorially independent magazine is published by Veen Media. It contains mainly translations of articles in the English-language edition, but also its own articles. These are typically focused on research in the Netherlands and Belgium, the main countries where it is purchased.

A Tom Gauld cartoon appears on the Letters page. A readers' letters section discusses recent articles and discussions also take place on the website. Readers contribute observations on examples of pseudoscience to Feedback, and offer questions and answers on
