Following a huge publicity campaign, the first issue of Eagle was released in April 1950. Revolutionary in its presentation and content, it was enormously successful; the first issue sold about 900,000 copies. Featured in colour on the front cover was the comic's most recognisable story, Dan Dare, Pilot of the Future, created by Hampson with meticulous attention to detail. Other popular stories included Riders of the Range and P.C. 49. Eagle also contained news and sport sections, and educational cutaway diagrams of sophisticated machinery. A members club was created, and a range of related merchandise was licensed for sale.
