The news: Substack is seeing positive results in the push to get creators to explore video content—but overall incorporation remains low.

• 6% of posts published in the first 10 days of March 2025 contained videos, per a Subalytics analysis of 63,000 newsletters reported by Digiday—an all-time high.
• Posts with embedded videos grew 135% YoY in February, but accounted for just under 91,000 posts out of roughly 2.8 million, representing only 3% of all posts.
