The partnership, signed in October this year, is a renewal of TCS' existing collaboration with Nielsen. The two companies had struck a 10-year deal in 2008 for USD 1.2 billion, which was expanded to USD 2.5 billion in 2013.
Under the new deal, the terms of the agreement have been extended for an additional five years so as to expire on December 31, 2025, with three one-year renewal options granted to Nielsen, the TV rating company said in a regulatory filing to the US SEC.
The filing stated that the Mumbai-based firm will globally provide Nielsen with professional services relating to IT -- including application development and maintenance -- BPO, client service knowledge process outsourcing, management sciences, analytics, and financial planning.
