It's really impossible to declare who the biggest in the world is. There are too many variables.
There are two variables, album sales and concert ticket sales around the world. Who ever has the best average of the two is the biggest in the world. That is the way its been determined since the late 1960s.
My point was that in 2000 before ATYCLB was released, U2 were not "relevant".
I don't have any evidence in terms of sales, or what most critics were saying that would indicate that.
Remember, that from October 1998 to October 2000, The Best Of 1980-1990 was a global smash hit selling over 10 million copies worldwide just in that time period. "Sweetest Thing", while not a hit in the United States, and just a slight remake of a B-side from the Joshua Tree, was able to chart well in other countries.
Whats your evidence that suggest they were not "relevant"?
Pop Mart only averaged about 30-35k fans per show in the U.S. I'm fairly certain N' Sync had better attendance numbers. If you were to take away U2's five biggest markets, you're probably looking at about an average of 25-30k per show.
Here are the statistic totals, averages for each leg of the POPMART TOUR as well as the totals and averages for the whole tour:
1ST LEG OF POPMART: 29 SHOWS
GROSS: $53,798,240 ATTENDANCE: 1,096,547
AVERAGE GROSS: $1,855,112 AVERAGE ATTENDANCE: 37,812
2ND LEG: EUROPE POPMART TOTALS
GROSS: $58,697,632 ATTENDANCE: 1,572,721
AVERAGE GROSS: $1,834,301 AVERAGE ATTENDANCE: 49,148
POPMART 3RD LEG: NORTH AMERICA 17 SHOWS TOTALS GROSS: $26,036,837 ATTENDANCE: 575,742 AVERAGE GROSS: $1,531,579 AVERAGE ATTENDANCE: 33,867
POPMART 4TH LEG: 15 SHOWS TOTALS

The Totals for the Entire 93 date POPMART TOUR are GROSS: $171,677,024 ATTENDANCE: 3,935,936 AVERAGE GROSS: $1,845,989.5 AVERAGE ATTENDANCE: 42,322
At $171,677,024, POPMART was the 3rd highest grossing tour in history as of October 2000, only surpassed by the Rolling Stones Voodoo Lounge and Bridges To Babylon/No Security.
If they had launched a tour in 2000, it would have done even less business.
What evidence do you base this on?
You can't tell me that those acts mentioned above couldn't sell out a couple arena shows per market back then (or at least come close).
Limp Bizkit and Korn would struggle to fill arena's at bargain basement ticket prices of $25 dollars in 2000. Britney Spears at the time had only been known to the world for 18 months was also in the same boat. Yes, all of them had strong album sales, but when it came to concert ticket sales, there were dozens of stronger artist. Not surprising given how brand new the artist were at the time.
In fact, the 2003 Metallica tour that had both Limp Bizkit and Linkin Park as opening acts had smaller attendance in some cities than POPMART.
N'Sync's 2001 stadium tour is competitive with POPMARTs 1997 performance in North America, but N'Sync were not popular enough outside North America to take this tour other places. Because of POPMART's greater success around the world outside of North America, the POPMART tour outgrosses what N'Sync did in both 2001 and 2002 combined.
U2 did not have a concert ticket sales advantage and they certainly didn't have an advantage in album sales or airplay.
Worldwide, U2 had a concert ticket sales advantage by a considerable margin over the artist you named at the time. POPMART was the third highest grossing tour in history as of the year 2000. While the POP album only sold 6 million copies, those sales are not poor either.
