The ballpark was built as a replacement for the Astrodome, the first domed sports stadium ever built, which opened in 1965. It is named for beverage brand Minute Maid, a subsidiary of The Coca-Cola Company, which acquired naming rights in 2002 for $100 million over 30 years. As of 2016, Minute Maid Park has a seating capacity of 41,168, which includes 5,197 club seats and 63 luxury suites.
