Mail Online (also known as dailymail.co.uk) is the name of the website for the Daily Mail, a newspaper in the United Kingdom. It contains almost all of the stories from the Daily Mail and includes a large archive of main stories. The Daily Mail's sister paper The Mail on Sunday has its own website, but the format and stories are basically the same.
The search engine on the Daily Mail website is also widely used, being one of Internet Explorer 7's default web searches, alongside names such as Google, Yahoo! and eBay. Most of the site can be viewed for free and without registration, although some services require users to register.
