Netflix’s new ad-supported plan was the least popular tier of its service in November, the first month in which the streaming giant offered it. The plan accounted for 9% of new Netflix sign-ups in the U.S. during the month. Some 57% of subscribers to the ad-supported tier in the first month were people re-joining the service or signing up for the first time, while 43% downgraded from pricier plans, according to Antenna.
