MediaPost clarifies iSpot’s MLB ad-spend methodology shift

MediaPost’s Wayne Friedman clarifies that iSpot’s 2025 MLB estimates included regional sports network data, while 2026 figures exclude RSNs, now classified “digital only,” comparing national linear-only spend of $358.76 million in 2025 to $319.96 million in 2026.

Why it matters. Buyers comparing MLB ad spend year over year must now account for a methodology change that reclassifies RSN inventory, since the same comparison without adjustment would overstate the 2026 decline.
