- Description: MediaPost’s Joe Mandese reports that Nielsen quietly announced new cross-platform “content measurement solutions” for early 2027, built on a “synthetic” fusion method called STAR that splits its 40,000-household panel up to 30 times to match streaming platforms’ server-log data.

**Why it matters.** Advertisers risk comparing incompatible “bespoke” audience numbers across platforms as Nielsen tailors methodology and fees to individual streaming providers rather than a single market standard.
