The BBC have been gradually investigating and adopting responsive web-design techniques to their news website, focussing on the mobile variant of the site. Initially I thought they were missing a trick by excluding desktop users from the benefits of responsive web-design. The reality seems much subtler however.
In essence they are able to gradually apply the responsive techniques on the mobile site, without disrupting their massive desktop audience and legacy publishing platform. Over time the responsive site gradually grows in scope and importance until it can ultimately become the overall site, including for desktop users. A notable side-benefit is a nicely phased migration from a legacy publishing platform without a big bang switchover and all the risk that would entail.
