Communications and IT service company CenturyLink has extended a naming rights agreement with CenturyLink Field, the home stadium of NFL American football team the Seattle Seahawks.

The new deal runs from the 2019 season through to the 2033 campaign and also covers the CenturyLink Field Event Centre.

The 67,000-capacity stadium, which is also home to Major League Soccer club the Seattle Sounders, will retain the CenturyLink name in its title.

CenturyLink will also retain its role as the exclusive communications services sponsor of CenturyLink Field and the Seahawks, while the company will continue to work with the team on various community programs.

The current naming rights agreement began in 2004 with the facility named as Qwest Field. However, CenturyLink took over as naming rights partner in 2011 after its acquisition of Qwest Communications.

Glen Post, III, chief executive and president of CenturyLink, said: “CenturyLink’s naming rights relationship with the Seahawks allows fans to have an enhanced game-day experience with secure, state-of-the-art stadium technology.”

The extended deal remains subject to approval by the Washington State Public Stadium Authority, the public corporation owner of both the stadium and event centre.

As part of an agreement with the organisation, 20 per cent of annual net profits generated from the Exhibition Centre are deposited into the State of Washington Permanent Common School Fund for public school improvements.
