Usher, Chris Brown make Billboard history

Atlanta's own Usher and R&B superstar Chris Brown are making Billboard history. The two singers have become the first co-headlining act to reach No. 1 on Billboard's monthly Top Tours chart since its launch seven years ago. Their tour generated an impressive $77.4 million in September alone, selling 423,000 tickets across 10 shows. With more performances ahead, including several in Atlanta, Billboard projects the tour could surpass $400 million in revenue and potentially challenge the record for the highest-grossing co-headlining tour in history.
