‘Masterchef’ Is Summer’s Biggest Series Debut

Fox scored with the debut of “MasterChef,” while “Breakthrough With Tony Robbins” tanked on NBC

A pair of reality shows featuring chef Gordon Ramsay led Fox to a primetime ratings win Tuesday night.

SUMMER SIZZLE Fox averaged a 2.8 rating/9 share in the key adults 18-49 demographic from 8-10 p.m. with two cooking reality shows — a new episode of "Hell's Kitchen" and the series premiere of "Masterchef." "Masterchef" scored a 2.7/8, making it the highest-rated series premiere on cable or broadcast so far this summer. "Hell's Kitchen" posted a 2.8/10.

LEFTOVER LUCK ABC grabbed the No. 2 spot with reruns of the game show "Wipeout" and the ABC News special "What Would You Do?" Overall, ABC averaged 2.0/6 from 8-11 p.m. 

BROKE NBC earned a third-place finish for the night, but the numbers didn't look good for the network. "America's Got Talent" scored a respectable 2.5/7 from 9-11 p.m., but the episode was the show's lowest-rated of the summer, down 17 percent from last week. The series premiere of "Breakthrough With Tony Robbins" posted an abysmal 0.8/3 from 8-9 p.m. "Breakthrough's" ratings were 69 percent lower than the numbers for NBC's last new reality show premiere, "Losing It With Jillian."

HARD DAY'S NIGHT CBS landed in last place for the night with repeats of "NCIS," "NCIS LA" and "The Good Wife." CBS averaged a 1.2/4 Wednesday night, behind all four major broadcasters and Spanish-language channel Univision. CBS has finished last on Tuesday for five weeks in a row.
