TNS, one of the world leaders in market research, introduced a new corporate identity a couple of months ago. The odd shape it has used until now has been straightened out to a square, and the lowercase letters have been exchanged for uppercase ones with more authority. The signature deep pink colour remains.
The previous identity was launched in 2003, when company went from being Taylor Nelson Sofres with several local names, to one unified TNS. Wolff Olins was the agency behind that rebrand.
The new look was launched in March or late February. There doesn't seem to have been any formal announcement of the new logo.
