A promising (and rare) second-week lift for NBC’s new summer series Food Fighters (1.3). The 8 PM reality show hosted by Adam Richman was up 30% from its debut last week. America’s Got Talent (2.4, 10.5 million) was even with last week and once again the highest rated program of the night in adults 18-49 and total viewers. With Food Fighters as No.2 in 18-49, NBC easily won the night in both 18-49 (2.0) and viewers (8.6 million). The English-language broadcast networks offered an all-reality menu last night, with ABC’s Extreme Weight Loss (1.1) and the finale of Celebrity Wife Swap (1.0) as the only other originals. Both were up a tenth from last week, with Celebrity Wife Swap down a tenth from last summer’s finale, which aired at 8 PM. Univision finished second to NBC for the night in 18-49 (1.4), followed by ABC (1.0), CBS (0.9) and Fox (0.6).
