Clarke (pictured), who will take up her new role immediately, will lead the Nielsen Media thought leadership team and will be charged with setting a global strategy for content. She will report to Nielsen’s head of global communications, Laura Nelson.

Nielsen announced its intention to split into two businesses in November 2019, with Nielsen Global Media focusing on media market metrics.

Before joining Nielsen, Clarke was at Black Enterprise, where she was founder and chief brand officer of Women in Power, which included a television show, annual conference and multi-platform content.

Clarke has also worked as a newspaper reporter, magazine, editor, television producer and host, and has had two books published.

Nelson said: “As Nielsen continues to revolutionise its leading measurement solutions in order to account for fundamental shifts in audience behaviour, Clarke will be instrumental in reshaping Nielsen’s thought leadership and content.”
