[...] to the BBC as an independent public broadcaster.
In most countries, organizations funded by taxes would be called governmental ones.
That is probably correct, for most countries. But it gives you a tilted view of the consequences. BBC, NRK (Norway), SVT (Sweden) and a few other broadcasters are financed through the tax system, rather than commercials. They are controlled by independent bodies, which does not control the money. That gives you two major benefits. One; There are no commercials (American TV is totally wrecked by commercials), and you can watch a program from start to finish without numerous noisy commercial interrupts. Two; Because they have a fixed and firm budget, with clear rules to also serve the niches, they produce programs without being slaves to viewer volumes.
So summing up, BBC, NRK and SVT are a lot more independent than a commercially driven broadcaster. Wether it is public or governmental is academic.
