Amazon's The Grand Tour has raced to the top of the viewing chart on the platform in both November and December.
According to global market research company GfK, the series, fronted by Jeremy Clarkson, Richard Hammond and James May, became the most-streamed show on Amazon in November 2016, accounting for eight per cent of all the streams watched.
In December, that increased to 17 per cent of all streams, placing the show well ahead of The Man in the High Castle, which attracted nine percent of all streams viewed.
GfK estimates that if the figures were equated to viewer numbers, the show's audience would be around 2.3 million viewers - significantly less than 5.8 million who watched Clarkson, Hammond and May's final episode of Top Gear in June 2015.
GfK's research also suggests The Grand Tour is leading more people to sign up for the OTT service.
Christopher Smith, senior research executive in GfK’s brand and customer research division, comments, “Our analysis proves that the high production costs for TGT are paying off, with viewers of the show agreeing that Amazon’s investment has been worth it.
