The WPP group has acquired Bangalore based design firm Ray + Keshavan. The group had got the approval from the foreign investment promotion board (FIPB) a while back and this acquisition marks the group's entry into the specialised design market in India. Ray + Keshavan has so far done work for companies like Himalaya, Wipro, Infosys, Hindustan Lever and ITC and offers services like brand identity, interactive design, packaging and environmental graphics.None of the existing WPP group firms in India currently have specialised design functions and this acquisition would broaden the services offered by the group in India. The firm reportedly has a revenue of Rs 25 crore and the acquisition is likely to give it opportunities in the international market.
