Nielsen correction bumps up publisher audience numbers

Publishers have seen a jump in unique audience numbers as Nielsen re-releases its April measurements after identifying a data production issue.

The data analyst company identified the issue after an investigation into major slumps, which affected the unique audience numbers of most publishers. The reduced numbers were first attributed to the holiday period before it was realised that smartphone and tablet audiences were incorrectly recorded for the 10-day period from April 20 to April 30.

While most of the 3,285 brands were impacted by three per cent, 287 brands were hit by more than 10 per cent.

The chart below details how the unique audience data of the top 10 brands was impacted.
