    I did not see any update for 2009 regarding Closed Captioning?
    I do see that susposedly since 2006 ALL programming is suposed to CC.. I wonder what the exceptions are????
    I have noticed many programs that are not Captioned still????
    Is this possibly a Technical error?? or the program was not Captioned to begin with?? It saddens me that Programming Providers could care less if the Deaf are able to get anything out of the TV programs. Granted a lot of the programming is trash, but even many of the educational and public service programs are not CC.?
