Formation
Nielsen was founded in 1923 by Arthur C. Nielsen, Sr., who invented an approach to measuring competitive sales results that made the concept of " market share " a practical management tool. The holding company was incorporated in the Netherlands and later was purchased on May 24, 2006, by a consortium of private equity firms.
Merger and listing
In January 2011, Nielsen consummated an initial public offering of common stock and, subsequently, started trading on the New York Stock Exchange under the symbol "NLSN". On August 31, 2015, Nielsen N.V., a Dutch public company listed on the New York Stock Exchange, merged with Nielsen Holdings plc, by way of a cross-border merger under the European Cross-Border Merger Directive, with Nielsen Holdings plc being the surviving company. The merger effectively changed the place of incorporation of Nielsen's publicly traded parent holding company from the Netherlands to England and Wales, with no changes made to the business being conducted by Nielsen prior to the merger.
2021 split and 2022 buyout
On March 5, 2021, Nielsen Holdings announced the completion of sale of Global Connect business (known as NielsenIQ, the former AC Nielsen) to private equity firm Advent International. This transaction effectively turned Nielsen into a pure-play media audience measurement and analytics firm.
In March 2022, Nielsen announced that it had accepted a $16 billion offer from a group of private equity investors led by Elliott Investment Management subsidiary Evergreen Coast Capital Corp., and Brookfield Business Partners. The Nielsen board of directors had turned down an initial $9 billion offer from the investment consortium. The transaction was completed in October 2022.
