After several years in development, first at NBC and then at History, the U.S. adaptation of the hit British unscripted series Top Gear made it on the air last night. The History series debuted to respectable ratings – 1.9 million viewers, 1.1 million of them in the adults 18-49 demo. It didn’t come close to breaking any records though – for instance, History’s American Pickers drew 3.1 million in its series premiere earlier this year.
