Top Gear is a British television series about motor vehicles, primarily cars, and is the most widely watched factual television programme in the world. It began in 1977 as a conventional motoring magazine programme. Over time, and especially since a relaunch in 2002, it has developed a quirky, humorous and sometimes controversial style. The programme is currently presented by Jeremy Clarkson, Richard Hammond and James May, and has featured at least three different test drivers known as The Stig. The programme is estimated to have around 350 million views per week in 170 different countries. First run episodes are broadcast in the United Kingdom on BBC Two and (from Series 20) BBC Two HD. From Series 14 until Series 19, prior to the launch of the dedicated BBC Two HD channel, new episodes were also simulcast on BBC HD. The series is also carried on cable television systems in the United States via BBC America, in Latin America via BBC Entertainment and in Europe via BBC Knowledge. Series 22 started with the Patagonia special in two parts over Christmas 2014. Part 1 aired on Saturday 27 December and Part 2 aired on Sunday 28 December. The remaining ten episodes will go to air from Sunday 25 January onwards. The programme has received acclaim for its visual style and presentation, and criticism for its content and often politically incorrect commentary made by its presenters. Columnist A. A. Gill, close friend of Clarkson and fellow Sunday Times columnist, described the programme as “a triumph of the craft of programme making, of the minute, obsessive, musical masonry of editing, the French polishing of colourwashing and grading”.
