Viaplay chief commercial officer Ira Gladnikoff has been appointed head of the company with immediate effect.
She succeeds Jonas Karlen, who has decided to leave the company.
Gladnikoff first joined the Nordic streaming service in 2015.
Anders Jensen, MTG EVP, chairman of the Nordic entertainment management board and MTG Sweden CEO, said: “We wish Jonas well in his new ventures and thank him for his nine years at MTG and leading the successful development of Viaplay.
"It is great that we have a ready-made successor in Ira, who has extensive experience in the online video entertainment space and, as CCO of Viaplay, has been responsible for so much of Viaplay’s commercial success."
Gladnikoff added: “Viaplay is a passion of mine and I couldn’t be more excited about the opportunity to lead such a great team.
"We provide our subscribers with a more varied streamed content experience than any other service, and there are so many opportunities to work with our fellow MTG Nordic entertainment brands to deliver even more integrated and engaging entertainment experiences – this is just the beginning.”
