They work in fields such as fast-moving consumer goods, impulse products, beauty and personal care, fashion, baby, telecommunications and entertainment.

Kantar Worldpanel's first panels were founded in the 1940s by companies like Attwood Statistics Limited in the UK (1948) and Secodip in France (1969).

In 2000, IBOPE, NPD and TNS created the LatinPanel joint venture, representing the existing Brazil, Argentina and Chile operations.

In 2004 TNS acquired two additional companies, Data in Central America and CIMA in Colombia and Venezuela, bringing their consumer panels into the regional network.

In North America, as a result of the Taylor Nelson Sofres' acquisition of NFO in 2003,[2] the beverages usage panel was incorporated to the group.

In 2008, TNS was bought by WPP,[3] which resulted in the strategic decision to create a stand-alone company, branded Kantar Worldpanel, focused on consumer panels.

[4] In 2012, a new strategic tie up with another Kantar company, IMRB, led to the integration of their consumer panel in India into the Worldpanel network.
