For clarification, the ITU only specifies the first three characters in US 
call signs.

If I remember correctly, the US has KAA through KZZ, NAA through NZZ, and 
WAA through WZZ.  Countries are allowed to extend these call signs (thereby 
extending the space), and so in the US we have mostly 4 letter FCC assigned 
call signs, like KQED and WNBC.  (I believe, also, that these are more 
formally known as KQED-TV and WNBC-TV to distinguish them from their radio 

Interestingly, according to the ITU, the call letters BBC is actually the 
property of The People's Republic of China, who control BAA through BZZ.
