Pubs within a chain will usually have items in common, such as fittings, promotions, ambience and range of food and drink on offer. A pub chain will position itself in the marketplace for a target audience. One company may run several pub chains aimed at different segments of the market. Pubs for use in a chain are bought and sold in large units, often from regional breweries which are then closed down.

Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system.
