The stadium was originally known as Ravens Stadium at Camden Yards, until PSINet acquired the naming rights in 1999, naming it PSINet Stadium, it then reverted back to Ravens Stadium in 2002 until M&T Bank bought the naming rights in 2003.
M&T Bank Stadium opened to a full-capacity crowd on Sunday, September 6th, 1998 with the kick-off of the first official National Football League (NFL) game at Camden Yards. The Ravens played against the Pittsburgh Steelers in that game with a score of 20-13. The event marked the culmination of efforts begun in 1984 to return the NFL to Baltimore.
