in the United States, everyone knew and cared about the names of the companies on their stadiums, but no one knew or cared about the names of the companies on their players’ jerseys. There was no rule of human behavior that made this so: in Europe everyone knew and cared about the names on the players’ jerseys but not about the corporation the stadium was named for. There was no moment at which Americans had agreed on the importance of the stadium sponsors: it had just somehow happened. “And once everyone agrees on what matters, it gets repeated,” said Sam.
