Monday night's one-off special rated below most previous editions of the hit Cutting Edge spinoff, but still averaged a strong 3.57 million (15.8%) in the 9pm hour, adding 505,000 an hour later on +1.
Charlie Brooker's anthology series Black Mirror followed with a decent 1.27m (7.4%) at 10pm (+1: 223k), its second largest audience but down around 500k on the show's first ever screening in December 2011.
Elsewhere, Lewis drew 5.9m (22.9%) for potentially its final ever edition, although ITV didn't advertise it in any way as such.
Perhaps poignantly, Lewis won the 9pm slot for the first time this year as Penguins: Spy in the Huddle - which managed a respectable 4.57m (17.8%) - replaced BBC One's popular comedy schedule.
BBC Two's 8pm hour continued to thrill as University Challenge interested 2.89m (13.5%) and 2.47m (9.6%) watched Food and Drink half-an-hour later, the latter nearly matching Panorama which could only muster 2.69m (9.5%) for BBC One.
Cornwall with Caroline Quentin got the better of University Challenge without too much problem however, attracting 3.59m (14.3%) to ITV at 8pm and 145k on +1.
Over on 5, Police Interceptors logged 966k (3.8%) from 8pm, after which countdown show Britain's Best Comedy Characters amused 674k (3.7%).
This meant Sky Sports 1 finished above the network with a 3.7% primetime share for its Monday Night Football, with Channel 5 only managing 3%.
Thanks in large part to Corrie and Emmerdale, ITV won last night's primetime ratings battle with 24% (+1: 1%), leaving BBC One trailing with 19.6%. BBC Two edged Channel 4 to third place with 7.3% versus 6.7% (+1: 1%).
