News of Nielsen's potential appointment follows UKOM chairman Mark Cranmer stepping down from his position due to commitments with his new job as chief executive of Aegis-owned Isobar.
UKOM - a joint initiative between the IAB and Association of Online Publishers (AOP) - has moved into a critical stage of its development and has enlisted the help of the IPA and ISBA to facilitate a debate within the marketing community to drive the development of the planning currency.
The body is now in the final stages of bringing together media owners, agencies and advertisers to reach clear consensus and widespread support. A final announcement will be made in July on the official status of the currency.
UKOM was formed in December following the collapse of JICIMS (the Joint Industry Committee for Internet Measurement Systems) with the IPA and ISBA resigning as shareholders, leaving the IAB and AOP to form the new body.
The move came as the four companies would not commit to the estimated £15m required to fund the initiative for three years.
