Peshawari I have lived in the US for eons, and PBS and NPR are brilliant. They are not under constant threat, they have to work hard for their money. As any company ought to. (except apparently the fat cats at BBC).
I have voluntarily contributed to PBS and would never do the same for BBC. Anyway, irrespective of what you or I think, most people in the US rate PBS and NPR very highly. From the PBS website:
Over the course of a year, 89% of all U.S. television households - and 220 million people - watch PBS. The demographic breakdown of PBS' full-day audience reflects the overall U.S. population with respect to race/ethnicity, education and income. (Nielsen NPower, 9/19/2011-9/23/2012)
82% of all kids age two to eight watchec PBS during the 2011-2012 season. (Nielsen NPower, 9/19/2011-9/23/2012)
PBS had five of the top 10 programs among mothers of young children in September 2012, and the top six programs for kids age two to five. (Nielsen NPower, 9/2012)
PBS' primetime audience is significantly larger than many commercial channels, including Bravo (PBS' audience is 92% larger), TLC (86%), Discovery Channel (69%), HGTV (63%), HBO (61%) and A&E (29%).
In addition, PBS' primetime rating for news and public affairs programming is 88% higher than that of CNN. (Nielsen NPower, 9/19/2011-9/23/2012)
