britain’s best-loved orchestra

you’ve heard of a ‘band-in-a-box’ where a contemporary beat combo are loaded in to a small cardboard box where they play there music in glorious miniaturisation ?
well, no they’ve started doing the same with orchestras. the BBC concert orchestra parked opposite my office next to the Sony recording studios.
it’s britain’s best-loved orchestra apparently. how do they work that out ? is it totally amount of people that love them ? what if 100 people loved them, but only one REALLY loved them and the rest weren’t really that bothered ? would that make them more loved than the ITV orchestra which might be quite loved by73 people (who only listen for the adverts) ?
and wherever there are winners there are losers. so which orchestra is britain’s least loved ?
