The Office (UK)

This 12-episode original spawned adaptations in over a dozen countries, with the American version alone generating over $2 billion in streaming revenue. Concrete data: the UK original cost just £1.2 million to produce but launched a global phenomenon that now generates 1,500 times its initial investment annually.
