The Observer is a British newspaper published on Sundays. In the same place on the political spectrum as its sister papers The Guardian and The Guardian Weekly, whose parent company Guardian Media Group Limited acquired it in 1993, it takes a social liberal or social democratic line on most issues.
First published in 1791, it is the world's oldest Sunday newspaper.
The first issue, published on 4 December 1791 by W.S. Bourne, was the world's first Sunday newspaper.
Though early editions purported editorial independence, Bourne attempted to cut his losses and sell the title to the government. When this failed, Bourne's brother (a wealthy businessman) made an offer to the government, which also refused to buy the paper but agreed to subsidise it in return for influence over its editorial content.
As a result, the paper soon took a strong line against radicals such as Thomas Paine, Francis Burdett and Joseph Priestley.
After the paper was rejuvenated in early 2010, the main paper came with only a small number of supplements – Sport, The Observer Magazine, The New Review and The New York Times International Weekly, an 8-page supplement of articles selected from The New York Times that has been distributed with the paper since 2007. Every four weeks the paper includes The Observer Food Monthly magazine, and in September 2013 it launched Observer Tech Monthly, a science and technology section which won the Grand Prix at the 2014 Newspaper Awards.
