Mellon Financial
The stadium's capacity fluctuated depending on the event being hosted, but was increased due to additions between 1972 and 1991. The arena originally consisted only of lower bowl seating, but over time, upper decks were installed in the arena's "end zones" to increase capacity. In December 1999, Mellon Financial purchased the Arena's naming rights in a 10-year, $18 million agreement, which renamed the arena Mellon Arena.
