Daily Mail to overhaul Sun?

Fascinating piece in today's Media Guardian about the possibility that the Daily Mail newspaper is within shouting distance of overhauling Rupert Murdoch's Sun in daily sales. This might not have too much news value for Americans, few of whom bother to read either publication (in paper or web versions). But on the other hand, it's worth pointing out that, if Americans do know anything about the sleazy British popular press, they're usually thinking about the Sun, which has for 30+ years represented one "end" of the UK's popular-quality divide. If its primacy is about to be dislodged, that's quite significant, even in the States. The same piece, btw, also gives some useful historical context about the UK press over the past century.
