You can doubt it if you want, but it doesn't change the facts.
Prove it or at least base it on your listening to the various foreign language services.
Are you seriously telling me that you don't know about the BBC External Serivces' role during World War 2? Are you seriously saying that you don't know that the Russian Service would broadcast propaganda during the Cold War?
Are you telling me that you don't know that the BBC would broadcast material during their broadcasts on the various foreign language services that came not from BBC journalists, but from the Foreign Office? It's part of the reason why Britian is so popular not just with foreign tourists, but with refugees.
Again, I am shocked. Shocked that there are people out there who claim an interest in the broadcasting industry, who know little about its actual history.
But then, I guess this is the world we live in today. If it ain't written on the internet, it didn't happen, even though a lot of what is written on the internet also didn't happen, and in a lot of cases, isn't even based on anything even approaching reality.
