you say that it's hard to market Djoko-Murray and you imagine that the ATP could "make sure" that "tennis news get into general sports news on ESPN and the newspaper" ? I don't see the logics in that, there's no way to force newspapers, esp. in the US where you come from where tennis marketting seems to have big problems comparing to other sports.
In France and probably in the whole Europe, tennis is widely in sports news, and surely not because of the ATP, but just because people like tennis in our continent
Situation in the USA is much more dire than in France, as you can probably guess after 5 straight years of Monday USO finals
for example, I'm a big Isner fan. You would assume that Isner, being the best hope for american tennis, having been in a legendary match, and beating Djokovic in an epic masters 1000 SF last year would be all over the news for the USO and given primetime coverage. Well, you would be wrong, instead he was put after a terrible Shriekapova match and lost in meek fashion at 2am on a Monday night. The rest of the USO was the typical disaster, only saved in the news media by the retirement of Roddick giving tennis the spotlight for a fleeting moment.
Not all of this is the ATP's fault. One of the problems is the lack of coordination between the various country organizations (the USTA is a disaster obviously), the WTA which is dragging the ATP down with the weight of it's corpse, the tournament organizers, the different levels of the game (challengers, main tour, slams) seem to have no coordination at all. The ATP is simultaneously too big and bloated an organization to efficiently do anything and too small an organization to run the different levels of tennis in a profitable and organized manner so that challengers build into 250s build into masters build into slams.
But I'm getting off topic so I'll stop here, you got me ranting sorry
