Marketing a new investment can be difficult, perhaps particularly in the sports world. Fans don’t typically take change well, and interest can wane easily, etc, etc. That is, unless you happen to be Jay-Z. The mogul is supporting his recent co-ownership of the New York Nets with a set of shows – set to take place at the team’s new headquarters, the Barclay Center. Can’t think of many ways to better let people know there’s a new stadium in town than Hov performing. The dates of the shows shall be September 28-30, a general sale will begin this Friday the 13th, with tickets said to be under $30. Win win.
