The comic climate has changed somewhat and the likes of Little Britain do give a nod to 70s shows like Benny Hill, The Two Ronnies and Dick Emery. I think the show was trying to gauge if the youth of today are more prepared to accept Benny Hill having been accustomed to the likes of Sasha Baron Cohen and his postmodern politically incorrect humor.... although Cohen, Gervais et al do disguise it as irony.
Felt it was a bit hard to judge Benny's material as it obviously looked dated and most sketch shows by their nature are hit n miss affairs. I'd like to see more of Benny's BBC material but I gather the majority of it would have been wiped.
