Two things are true about webinars in 2026, and they sound like opposites. The first: live attendance has been falling for years, the inboxes are exhausted, and the hour-long broadcast that three people watch live is a punchline. The second: the platforms report record volume, rising average audiences, and conversion rates most channels would envy. Both are real. The reconciliation is that the thing called a webinar today is not the thing that was called a webinar in 2020. The live event died. The asset survived by becoming something else.
What 2020 did, and what 2022 undid
The inflation is well documented. As marketing leader Jaina Mistry wrote in a May 2025 MarTech piece, before 2020 webinars were a minor content type and businesses relied on in-person events. The pandemic changed that overnight: “virtual events exploded as businesses pivoted from in-person gatherings,” and “even Zoom added webinar hosting capabilities.” It was cheap to host a session that pulled in hundreds or thousands of leads. Then the overcorrection. In Mistry’s own blunt phrasing, “We killed the webinar. We overdid it. We flooded inboxes with invites and turned thoughtful educational experiences into thinly veiled product pitches.”
The attendance numbers tracked the fatigue. Mistry reports that in 2024, 25% of organizations ran 50 or more webinars a year while attendance “dipped to under 30%, down from roughly 50% in previous years.” A 2026 Booming Venture analysis puts a sharper line on it, citing ON24’s 2024 benchmarks: average live attendance fell to about 40% of registrants, “down from 51% in 2021.” The exact figure depends on what you measure, but the direction is not in dispute. Fewer of the people who register show up live, and the ones who do, per GoTo’s 2024 data as relayed by Booming Venture, “drop in late and leave before the demo.”
Why the calendar reclaimed the hour
The collapse was not a mystery of taste. It was a collision of three forces, and they are worth naming because they are not reversing.
The first is calendar load. Booming Venture cites Microsoft’s 2023 Work Trend Index finding that knowledge workers attend 60% more meetings per week than in 2020. An hour-long live webinar competes against that wall of meetings and usually loses. The second is AI compression. The same analysis notes that tools like Otter, Fireflies, and ChatGPT now summarize an hour-long session in seconds, which removes the reason to sit through forty-five minutes of slides to reach the one useful chart. The third is buyer behavior. Booming Venture cites 6sense data that 84% of buyers complete their vendor shortlist before they ever raise a hand. A live event optimized to capture a hand-raise is built for a moment that, for most buyers, has already passed.
None of those forces argues that the content is worthless. They argue that the live, synchronous, hour-long delivery of it is the wrong container.
The format that did not die
Here is where the platform data stops contradicting the obituary and starts explaining the resurrection. The ON24 2025 Benchmarks Report, summarized by MarketingProfs, analyzed millions of 2024 data points and found that 56% of attendees joined live, 45% joined on-demand, and 1% joined both. Read that against the attendance-collapse data and the picture resolves: nearly half the audience is no longer attending the event at all. They are watching the recording, on their own schedule, after an AI or a colleague told them it was worth the click.
The operators who run webinars at scale have already reorganized around this. Booming Venture’s summary of the shift is that “most pipeline now comes from on-demand clips, not live attendance,” and that the webinar “functions less as a live event and more as a content factory feeding clips, on-demand replays, and sales enablement assets.” The live session is no longer the product. It is the raw footage. Goldcast, whose 2025 B2B Webinar Benchmark Report draws on more than 19,000 webinars, sells the repurposing step as a core feature, turning a recorded session into clips, blog posts, and social cuts. That is the tell. The benchmark vendors no longer measure a webinar by who showed up. They measure it by how many assets it produced.
The live session is no longer the product. It is the raw footage.
The one live shape that still converts
If the broadcast model is dead, why do some live sessions still pull four-figure and five-figure audiences? Because they are not broadcasts. They are events with a genuine reason to be live.
The outliers in the data are instructive. Per the geisheker.com summary of Goldcast’s 2025 dataset, Capital Group’s 2025 Outlook webinar registered more than 64,000 people and pulled roughly 4,000 live attendees, the largest in Goldcast’s benchmark set. The HubSpot “Science of Timing” session drew nearly 25,000 registrants and almost 10,000 live, per a MarketingSherpa case study cited in the same piece. These are not product demos dressed as education. They are high-utility sessions tied to a specific, time-sensitive question, promoted as systems rather than calendar invites. The same source notes ON24’s 2025 finding that 35-to-45-minute sessions now outperform 60- and 90-minute ones on retention, and a 2026 Contrast survey of 524 B2B SaaS marketers finding educational sessions generate 53% more ROI than product-demo webinars. Shorter, genuinely educational, and worth a calendar slot. That is the surviving live shape.
Chris Walker’s trajectory shows the same logic from the operator side. Walker founded Refine Labs in 2019 and, by the agency’s own account, built it by challenging the lead-gen model. His distribution engine, as Lemonpie documented, was a podcast and a weekly live Zoom series, repurposed and “dripped out on LinkedIn over time,” with “no outbound sales.” That is the content-factory model in its native form: produce once, syndicate as clips, let the recording do the work the live event used to. More recently, in a shift reported in a widely shared LinkedIn post, Walker argued that “in the age of AI, sharing your playbooks might be a disadvantage,” and moved toward “more private live webinars with his target audience.” The live session comes back precisely where the value is in the room and cannot be compressed into a clip: small, gated, and interactive.
When to use which
The decision is no longer webinar or not. It is which job you are hiring the recording to do, and whether the live moment adds anything a clip could not.
Run a live session when the value is in real-time interaction: a private session for named accounts, a genuine Q&A with an expert your audience already wants, a time-bound topic like an annual outlook where being early matters. Keep it to 35 to 45 minutes, because the data says the back half of the hour is where people leave. Treat everything else as production. Record it, cut it, and accept that 45% of the audience, per the ON24 mix, will meet it on demand and on their own schedule.
What does not work anymore is the default: an hour-long gated session built to harvest registrations, measured by lead count, sent to a list that has seen forty invitations this quarter. Mistry’s line holds. The audience did not leave because attention spans shrank. They left because, as she put it, expectations rose and most webinars stopped being worth the hour. The format that replaced the broadcast keeps the camera on and throws away the calendar invite.
