iSpot has clarified its advertising revenue methodology for the 2026 MLB season by restricting its reporting to live national linear games. The update shifts regional sports network data to a digital-only classification, resulting in a restatement of figures.
Why it matters
By narrowing its parameters to live national linear broadcasts, the company aims to provide a more specific look at advertising performance. This change necessitates a direct comparison between the adjusted 2026 data and the updated 2025 baseline.
The 2026 forecast includes 43,333 airings and 31.9 billion impressions, compared to 52,028 airings and 40.8 billion impressions during the 2025 season. The figures strictly cover live national linear content.

Market Landscape
This story follows a pattern set by the ongoing industry-wide shift toward fragmented media measurement standards as companies refine how they categorize digital versus linear reach. Such adjustments underscore the competitive pressure to provide granular data in an increasingly split media ecosystem.
Advertisers and media analysts should be aware that historical comparisons for MLB ad revenue will now reflect this narrower focus on national linear games. This change provides a cleaner, more targeted dataset for those tracking national broadcast spend versus local or digital inventory.
The takeaway
When analyzing advertising industry reports, it is essential to check if data includes regional networks or only national linear slots. Readers can implement this by verifying the scope of reporting periods before comparing year-over-year revenue trends.
