The new agreement extends the relationship between the two organisations which begun in 2003.

The focus of work will be to help the IPC optimise its commercial strategy leading up to Tokyo 2020. 

Nielsen Sports will help to analyse new revenue streams for the IPC, potentially creating a blueprint for National Paralympic Committees.

Examples include identifying best possible target groups and embedding partners and sponsors into social communications.

"We have had a great working relationship with Nielsen Sports for over 15 years," Xavier Gonzalez, chief executive of the IPC, said.

"Their unrivalled insights and expertise in sports, and more importantly, International Federations, has given the IPC the foundation to continue to promote and drive forward Para-sports.

"Nielsen Sports’ global network of experts allows us with confidence to access their industry leading solutions for any sport in any market in the world.

"This is such an essential factor for us, especially in the build-up to the Tokyo 2020 Paralympic Games."

As the IPC’s preferred research and consulting solutions partner, Nielsen Sports will also provide TV media valuation and market research.

For the first time, Nielsen Sports will also be providing the IPC with what is described as a comprehensive digital strategy as well as digital evaluation monitoring and measurement.

"We’re delighted to be extending our work relationship with the IPC, one of the world’s leading sports federations," Glenn Lovett, co-managing director of Nielsen Sports, said.

"Our consulting solutions combined with Nielsen’s analytical capabilities enable us to forge a robust commercial strategy for the federation.

"This will allow Nielsen Sports to support the IPC in better optimising its revenues ahead of the Games in Tokyo."

In May, it was confirmed that the IPC had chosen IMG Replay to be its exclusive worldwide archive partner.

The four-year representation agreement will see IMG Replay, home to the world's largest dedicated sports library representing more than 40 of the leading sports governing bodies, federations and events, market more than 8,000 hours of clips and programming dating back to the Rome 1960 Paralympics to the present day.

The deal includes archive footage from the next two Paralympics, Pyeongchang 2018 and Tokyo 2020.

Coverage of World and European Championships from some of the 10 sports for which the IPC acts as the International Federation - athletics, powerlifting, shooting, swimming, Alpine skiing, biathlon, cross-country, ice sledge hockey, snowboard and wheelchair dance sport - is also included.
