Britannica

Optical disc, online, and mobile versions

Britannica Online is a website with more than 120,000 articles and is updated regularly. It has daily features, updates and links to news reports from The New York Times and the BBC. As of 2009, roughly 60% of Encyclopædia Britannica's revenue came from online operations, of which around 15% came from subscriptions to the consumer version of the websites. As of 2006, subscriptions were available on a yearly, monthly or weekly basis. Special subscription plans are offered to schools, colleges and libraries; such institutional subscribers constitute an important part of Britannica's business. Beginning in early 2007, the Britannica made articles freely available if they are hyperlinked from an external site. Non-subscribers are served pop-ups and advertising.
