Well clearly it is popular entertainment because of the day/time slot it is given by the ITV schedulers every year, which just also happens (probably by coincidence) to be the most expensive day/time to run a TV advertising campaign - because its so popular.
As for whether or not it unearths some decent young singing talent every year, well that is down to individual choice but I happen to think it does and the only shame is that even just fifteen years ago there was a huge number of outlets where they could practice their trade professionally - and any of the finalists would have passed agents auditions to do just that.
Chart music sales isn't the only measure of professional success.
