The US Department of Justice has asked Ticketmaster and Live Nation for more information about their planned merger – the second time it’s made such a request – according to Associated Press. That suggests it’s taking a detailed look at the deal – although this shouldn’t come as a surprise, given the size and importance of both companies in their respective markets. Meanwhile, Ticketmaster chairman Barry Diller has gone on the attack again over accusations that the company isn’t serving fans well enough, particularly around big gigs like Michael Jackson and Phish. “Oddly, the better we sell tickets, the more unpopular we become,” he says.
