The Currency Wars: Nielsen vs. VideoAmp vs. iSpot vs. Comscore
Despite VideoAmp, iSpot, and Comscore gaining JIC certification in 2024, alt currencies haven't shifted ad spend — Nielsen persists because measurement is structurally embedded in how TV deals are bought.
Scale
Multi-billion dollar TV advertising market; Paramount dropped Nielsen for VideoAmp in 2024
Before
Nielsen monopoly on TV measurement with panel-based ratings; no credible alternatives
After
VideoAmp + Comscore JIC-certified (April 2024); iSpot JIC-certified (August 2024) — but most buyers still transact on Nielsen
Key Insight
Why Nielsen persists is structural, not technical — measurement is embedded in the buy. You can't change the currency without renegotiating the deal structure.
In a Snowflake Conversation
The 'why isn't Nielsen dead' question is structural, not technical. The answer is that measurement is embedded in the buy — you can't change the currency without renegotiating the deal structure.
