The record label couldn't care less how much money U2 make on tour, they don't get the money from it. The record label probably want U2 to tour for free so people have more money for CDs
U2's last two albums sold over 20M combined (worldwide). I'm not sure how well NLOTH will do worldwide, but it's already up to 2M and the tour hasn't started nor has there been any real big hits from the album. Get a big hit, get the tour going and I can see NLOTH approaching those types of numbers.
Now if someone meant 10M just in the U.S. - uh, no. It will be interesting to see what Eminem's new album does, but I highly doubt it will be 10M.
And Irishteen is right - labels don't make money from tours. But artists tour because THEY make money from touring. In fact, most artists have their incomes generated from touring - not CD sales.
Record labels are in an uproar over illegal downloads for one reason - they aren't making money. Sure, they try to cover it up with the fact that it's illegal and violates copyrights and may hurt the artists, etc. But they wouldn't care about any of that if they made $$ (like with iTunes downloads). They care because they aren't making money.
Record labels are becoming a thing of the past. The future will most likely be only downloads. More and more artists will work on independent labels. They might connect with promotion companies, who help promote the release - but only if they also help promote the tour. This way the promotion company gets a cut of the real money - the tour money.
CD's still sell. I still like holding a CD in my hands. But I have to admit, that's mostly for the bands I truly love - and that's dwindled to U2. I still buy some CD's here and there, but mostly, I download too. If I want info. on a band, I look it up on a website.
If record labels and the RIAA were smarter, they would have jumped on something like iTunes well before Apple came up with it. Instead, they sued people and made a fuss. Fortunately, the RIAA has stopped the lawsuits (and it's probably because they were expensive for little return - and it didn't discourage people from illegal downloads).
Hit songs can still sell a lot (like Clarkson's and Eminem's latest) - in fact, some hit songs have sold over 2M legal downloads! U2 have had some big hits in the download world too. Hopefully they'll get one from this album. But CD sales - I'm hoping NLOTH eventually gets to 2X Platinum. I'll be thrilled with that.
