MailOnline: US Launch Outdoor Campaign, the online home of the British tabloid newspaper The Daily Mail, is seriously popular. In fact, it’s the world’s largest newspaper website by unique visitors, more popular in the United States than The New York Times, USA Today, and The Wall Street Journal. The purpose of this campaign (the brand’s first advertising in the United States) was to quickly introduce Americans to MailOnline using the unique blend of serious and popular news that makes the site so compulsively readable.
