Comedies do tend to pick up new viewers on repeat runs more than dramas I think. Especially as it's a young male targetted show, who likely wouldn't be watching ITV at 9pm on a Friday.
Of the 7.46m men aged 16-34 in the country, on average 1.79m were watching TV in the Friday 9pm slot during GNO
's run (inc same-day timeshift of course), and GNO
captured just 180k of them - a share of 10.0% and a TVR of 2.4. (Figures inc +1.)
How did the Beeb 3 Eastenders do please?
's repeat on BBC Three got 489k (3.0%).
