The combined worldwide ticketing company (which also manages music artists) and the major concert promoter would be called called Live Nation Ticketmaster.
Ticketmaster handles ticket sales for some Broadway theatres and national tour houses, but this potential merger would not significantly affect the traditional theatregoer.
The Wall Street Journal pointed out that the new company might be able to squeeze out competing concert promoters and dictate ticket prices to concert consumers.
Live Nation's market capitalization is $390 million; Ticketmaster's is $351 million, according to the Journal.
No official announcement of the merger has been made. In 2008 Ticketmaster acquired Front Line Management, the artist- management firm that handles hundreds of major concert performers.
Live Nation already has artists such as Madonna and Jay-Z in its stable.
