NBC Olympic theme song...?

Question

Is it used by broadcasts in every country as the Olympic theme, or just the U.S.?

Answer 1

I'm an American living in Brazil and I have to say that the inspiring athlete stories, Bob Costas and that famous NBC music we always associate with the Olympic Games are the big things I miss about watching the Olympics from another country!  

Answer 2

It's the national theme of the Olympics...of course all of the world.

Answer 3

Why would somebody else use a theme if it was exclusive to NBC?

Answer 4

There's actually two recognizable fanfares to the Olympics broadcast on American TV if you listen closely.  

The distinctive brass theme that is used to return from commercial breaks is called "Bugler's Dream" and was written by Leo Arnaud in 1958, first broadcast by ABC in 1968 and continued by NBC.  

The longer fanfare often used for athlete backstories and the like was written by John Williams as the official music of the 1984 games.

The two are sometimes combined for network coverage of the games ever since the 1996 Atlanta Games.

However, neither are official themes as approved by the Olympic Committee, and thus not internationally recognized.  The "Olympic Hymn" is the only anthem that can take that claim, which is played during the raising of the Olympic flag, and not nearly as catchy of a tune.
