L'Oréal’s decision came after a consolidation review process held between October to December last year.
In October 2010, Mindshare was already appointed the media agency-of-record for L'Oréal in China responsible for buying of traditional media (TV, print), and media analytics.
ZenithOptimedia has been the agency for digital media strategy and implementation before the shootout.
The win adds to the approximately US$1 billion media planning and buying account held by Mindshare.
"Mindshare now has significant responsibility to boost L'Oréal’s competencies and investments in the arena of online video,” said Karl Cluck, chief strategy officer, Mindshare North Asia.
Last year, the cosmetics brand spent about 10 per cent of its traditional TV budget on online pre-roll ads, and is set to increase its OTV adspend this year.
