Hello from Britannia!
The comedy at the core of the nation's conscience since 07/08 has been The Thick Of It. You may well have heard of it, its Armando Iannucci's opus, and the series from which the In The Loop movie was born.
Peep Show has continued to punch hard, too - definitely worth checking out.
And special mention goes to The Inbetweeners, a brilliant comic representation of lift in a British 6th form (school age 16-18, before going to University).
There has also been the excellent Down The Line on the radio, which has just made the jump to telly as Bellamy's People.
And if its standup you're after, the top dog for a while has been Stewart Lee.
