It is understood that Nokia will divide six global campaigns in various areas of its business between the two digital networks, which will be responsible for taking the lead on digital strategy, online advertising and web design.
Isobar and R/GA may also take on local work on specific creative projects. Nokia has previously appointed digital agencies on a local basis, such as the Swedish agency Farfar, R/GA in the US, and Agency Republic and Work Club in the UK.
Wunderman, which was appointed last year to handle the implementation of Nokia's global digital campaigns, will continue in this role.
In 2007, Nokia introduced a similar agency structure with its ad agencies when it selected Wieden & Kennedy as the lead global ad agency for handsets and JWT to implement the campaign across more than 80 markets.
