News Alerts – a no-brainer

Why is it still so hard to get these from most radio station websites? Even (especially) from News or News/Talk stations?
Isn’t it a natural way to communicate with listeners about stuff that matters to them – rather than you?
Isn’t it a natural mechanism to “boomerang” listeners back to the radio station, where the ludicrously low cost of such alerts can pay for themselves hundreds of times over?
