Bon Jovi's ending 2010 as the world's top-grossing touring act of the year.  Pollstar.com reports the New Jersey rockers earned 201-point-one-million-dollars for its "The Circle" trek, which launched in Honolulu, Hawaii last February.  Two other veteran acts are landing in the number two and three spots on the list.  The hard-rocking Australian band AC/DC grossed 177-million with its "Black Ice" tour in 2010 to capture second place.  U2 is third, pulling in nearly 170-million for dates this year on its "360 Tour."  The figure is even more impressive given the band had to scrap the North American portion of the trek after frontman Bono suffered a serious back injury while rehearsing for the tour.  Metallica grabbed the number five spot with 110-point-one-million dollars in sales in 2010 for its "World Magnetic Tour."
