Nielsen Holdings has announced its fourth quarter and full year 2017 results. Revenues were $1.761 billion for the fourth quarter of 2017, up 6.3 percent (or 4.2 percent on a constant currency basis), compared to the fourth quarter of 2016. Revenues were $6.572 billion for the full year of 2017, up 4.2 percent (or 3.8 percent on a constant currency basis) compared to 2016.

“We executed well on our key initiatives in Watch and Buy while contending with rapidly changing markets in 2017. In 2018, we’ll continue to invest in innovation to drive growth and efficiency as we proceed on the path towards 2020,” said Nielsen CEO Mitch Barns.

He continued, “In Watch, we had a strong year. Our teams were relentless in their efforts to enhance our Total Audience Measurement system and drive client adoption across all of its components. As the market further evolves due to ongoing media fragmentation, Total Audience Measurement will serve as the foundation for our future, providing the measurement capability, scale, and flexibility necessary to best meet our clients’ needs. In Buy, we remain well positioned in Emerging Markets due to our investments in coverage and our balanced client portfolio. In Developed Markets, the U.S. remains under pressure as clients persist in seeking efficiencies in their own businesses in a difficult growth environment. We continue to drive the rollout of the Connected System and increase coverage and granularity within our Total Consumer initiative, both of which will enable us to drive growth for Nielsen and our clients despite the environment.”
