Indeed, the original names of the BBC radio networks reflected this.  
The BBC's first network was the "Home Service."  Next they came up 
with the "Light Programme," which apparently was somewhat less 
"Auntie Beeb" than the Home Service.  Finally, they established a 
third network and called it the "Third Programme."  At some point, I 
think in the 1960s or 70s, the three netorks became "Radio One," 
"Radio Two", and "Radio Three," and a fourth network, "Radio Four," 
was added.  When I was in London in 1973, I heard program tests for 
Britain's first local radio services.

On shortwave, they once had the "Empire Service," which I think may 
have merged with something else to become the "General Overseas 
Service."  I remember hearing this when I first started listening to 
shortwave radio in the early 1960s.  Then the name was changed and it 
became the "World Service," as it is called now.
