The review covers media activity across all corporate campaigns that are planned from Kia's centre in Korea.
Vizeum handles the media for the car-maker's corporate activity in several European markets, including the UK. It has worked closely with Kia's in-house agency Innocean, which produces creative for the corporate campaigns and co-ordinates media activity.
Kia's local market media planning and buying, which is handled by OMD across Europe, is not included in the review. M2M, the OMD-owned agency, handles the £20 million UK account.
The review follows news of a pitch in the US to consolidate the combined $800 million US media accounts for Kia and Hyundai. Kia is also holding a global direct marketing pitch (Campaign, 21 September).
