The curtain is going up on Xfinity Live! — a 60,000-square-foot sports and entertainment center in the middle of South Philadelphia's stadium complex. Joel Maxcy of the Temple School of Tourism and Hospitality's Sport Industry Research Center says Xfinity Live! creates a sports shopping mall, with the major stadiums as anchor stores. "You're opening up related retail opportunities and things the sports consumer would like," Maxcy said.
