There seems to be something of a tendency for historical documentaries (about Britain) to announce that some aspect of the era under discussion is "the foundation of the modern world". In Rule Britannia! Music, Mischief and Morals in the 18th Century Suzy Klein's thesis was that the musical world of 18th Century Britain was the start of the music and entertainment business as we know it today.
The First Georgians: The Kings Who Made Britain was a series presented by Lucy Worsley which ties into an exhibition at Buckingham Palace this year to mark the 300th anniversary of George I taking the throne. The series (and presumably exhibition?) focussed on Georges I and II who are often overlooked a bit in the rush to get to George III and the madness and loss of the American colonies.
