Pretty Little Liars Ratings Season 4Pretty Little Liars was back for its fourth season last night with 2.972 million viewers watching. That’s up slightly from the 2.93 million total viewers the ABC Family flagship drama garnered in its Season 3 debut on June 5, 2012. However in key demos the 8 PM Season 4 premiere saw significant gains over last summer’s debut. Last night’s episode was up 31% among Adults 18-34 to 1.28 million over the Season 3 premiere for its best summer opener ever. The show was also up 15% among Adults 18-49 to 1.62 million and rose 11% in Viewers 12-34 to 2.11 million. In total viewers, PLL was the No. 1 scripted drama on cable on Tuesday. Unlike last night, that Season 3 premiere wasn’t up against an NBA Finals game but it did face basketball as the Miami Heat took on the Boston Celtics in Game 5 of the Eastern Conference. Tuesday’s Season 4 premiere of the teen thriller series, which featured computer hacking, a funeral and a body in a car trunk, was down from the 3.210 million viewers who watched the Season 3 winter return on January 8, 2013.
