Catchphrase 'Come in, Berlin!' originated in 1943 film "Tarzan Triumphs". How di

In this film, the German radio operator was trying to get hold of Berlin, repeatedly asking 'Come in Berlin'. It is now used quite commonly to make or remake contact with somebody after a lapse of time, but I can find very little reference to the origins of the phrase or how it came into common parlance.

I've never heard anyone say "Come in, Berlin!", so I don't believe that that precise phrase is in common usage.

However, people do say "Come in, [whoever]!" when they are trying to talk to someone who is apparently not listening, often followed by "Earth calling [whoever]!"

This use of "Come in..." is simply because that is what radio users have always said when making contact with each other, and probably has nothing to do with the old Tarzan film, as such.
