This fall’s Chicago marathon was the last under its current name. With the summer acquisition of LaSalle Bank by Bank of America, the annual race—called the LaSalle Bank Chicago Marathon since 1994—will become the Bank of America Chicago Marathon. While the bank didn’t need to pay a separate fee for the renaming, the switch continues a relatively recent trend, as companies have paid top dollar to put their names on some of the city’s most popular entertainment venues and events.
