iSpot has clarified its 2026 Major League Baseball advertising revenue data, revising its methodology to exclude regional sports networks from national linear game estimates. The updated reporting now focuses exclusively on live national linear broadcasts to ensure consistent year-over-year comparisons.
Why it matters
By removing regional sports network data from its national reporting, iSpot is narrowing its focus to pure national linear inventory to better reflect the specific market performance of major broadcasts. This shift changes how marketers evaluate national MLB reach and spending benchmarks versus prior periods.
The revised 2026 forecast estimates $319.96 million in national linear ad revenue from 31.9 billion impressions, compared to $358.76 million from 40.8 billion impressions in 2025. These adjustments follow the reclassification of regional sports networks into a digital-only reporting category.
The players
iSpot
An advertising measurement firm providing cross-platform television and video measurement services.
Major League Baseball
The professional baseball league overseeing national and regional broadcast rights for regular season and playoff games.
The details
iSpot is refining its advertising intelligence by isolating live national linear airings, a move that requires separating regional network data into a digital-only classification. This change removes variable regional broadcast footprints from the aggregate national total, providing a more precise view of national-level ad spending. Advertisers using these figures for budget planning must now account for this shift to ensure they are benchmarking against comparable, exclusively national performance data.

Market Landscape
This adjustment reflects the industry-wide move toward isolating fragmented digital-only assets from premium national broadcast inventory. iSpot's reclassification marks a tightening of methodology that helps operators differentiate between traditional linear spending and emerging digital broadcast models.
Marketers should update their 2026 media planning models to reflect the exclusion of regional sports networks from national league projections. Financial teams should ensure that previous year-over-year growth metrics are adjusted to align with this new, narrower national-only standard.
The takeaway
The move toward stricter segmentation of broadcast revenue data is a signal that precision in national benchmarking is increasingly prioritized over aggregate reach metrics. Operators should re-audit their internal marketing dashboards to ensure they are not conflating national linear figures with regional or digital datasets.
