As reported in the Telegraph, the deal with bet365 is for six years and also sees them extend their shirt sponsorship for a further three.
It has also been announced that the club will fill the gap between the DPD and Marston’s Pedigree Stands, taking the stadium capacity to more than 30,000.
Tony Scholes, Stoke City Chief Executive, said: “The Premier League is constantly evolving and to ensure that Stoke City remain as competitive as possible it’s important we explore as many ways as possible of generating revenue. As supporters are no doubt aware, the Britannia brand no longer exists and it was important that we attracted a new stadium naming rights partner.
“The Premier League is watched around the world and bet365 are a truly global company. We are delighted that we have been able to reach an agreement with them over the stadium naming rights for an initial six-year period, along with the extension of their shirt sponsorship agreement.
“bet365 are taking over from Britannia and I would like to take this opportunity to thank Britannia and the Co-operative Bank for their tremendous support over the past 19 years.
“We also felt the time was right to redevelop the corner of the ground between the DPD and Marston’s Pedigree Stands. Planning permission has been in place for some time, but it was important we carried out the work when we felt the club was ready for an increase in seat capacity.”
