Nielsen has delayed its monthly Gauge report to April from its planned release next week due to client complaints about the company's updated methodology. The report, along with the monthly Media Distributor Gauge Report, had been scheduled to come out on Tuesday, earlier than usual. The company will now be released in April. The Gauge began in 2021 as a way of tracking contemporary TV viewing, which increasingly straddles linear and streaming. The change involved replacing some of Nielsen’s own panel data with numbers from the Advertising Research Foundation tracking how various demographic groups watch programming via different technology. Despite these challenges, Nielsen believes this is the best and least disruptive path for the industry.
