Attendees don’t remember an entire 60-minute webinar. They remember moments.
That was the takeaway from Brian Cleary’s session at Content Marketing World earlier this month. Cleary, global marketing director of assurances and life sciences at NSF, pointed out that the average employee gets interrupted 275 times a day. An hour-long webinar means roughly 30 of those interruptions, plus a heavy cognitive load as attendees try to hold everything from minute 1 to minute 60.
“As much as we like to think our prospects are sitting there five minutes before the webinar starts waiting to hang on every single word, it simply doesn’t happen,” Cleary said. “It doesn’t happen because the days of uninterrupted attention are truly over.”
The Fix: Shorter, Modular, and Podcast-Style
Cleary’s team rebuilt webinars around three changes:
- Shave off 30 minutes. More people can give you 30 minutes than commit to giving you 60.
- Ditch the lecture format. Faces on a screen in a podcast-style conversation, with an interviewer keeping time, beat dense PowerPoint slides.
- Break it into modules. Each module is only six to seven minutes long and ends with a quick recap. “If you’ve zoned out or get distracted during the webinar, this lets you come back without feeling like you’re at a disadvantage,” Cleary said.
The Structure Inside Each Module
Every module follows the same three steps:
- Relevance: Lead with the headline, just like Netflix opens with the big dramatic scene. For example: “The 2016 pharma legislation has been updated. Here are the four main changes.”
- Context: Explain why it changed. Drug manufacturing is a good example, as GLP-1 demand has pushed production well beyond what the old model was built to handle.
- Synthesis: Say what it means for the audience. If you manufacture pharmaceuticals for the U.S. market, you must update your quality management system and marketing authorizations by a set date or you can’t trade.
The synthesis step answers the question every attendee is silently asking: what’s in it for me?
Analyzing the Results
Since moving from 60 minutes to 30 minutes and adopting the modular format, NSF has seen a 41% increase in webinar registrations.
The format also made content easy to reuse. Cleary’s colleague, Marie, took part in a January webinar on AI in human decision-making in pharmaceutical manufacturing by contributing an op-ed and a case study. NSF stitched those two modules together into a new webinar for a European audience in July.
“We ran it at 12:45, and we thought it would be similar to a learning luncheon,” he said. Six or seven people at several large manufacturing sites joined individually from their desks, then gathered in the canteen to discuss it afterwards. Many then contacted NSF’s sales team to learn more.
The second webinar run generated more than 500 marketing qualified leads (MQLs), meaning prospects who showed enough interest were handed to sales. In NSF’s business, a single lead can be worth tens of thousands of dollars or more.
Measure Value, Not Minutes
Cleary used to judge webinars by how many people stayed until the end.
“When I was a junior marketer, people would avoid me after the webinar ended because I would be in the depths of despair,” Cleary said. “I beat myself up because I was basing everything on whether people stayed.”
In an attention economy, he now considers that to be the wrong question. His team asks instead whether attendees got value.
“Where there’s value for the people attending, there is follow-on value for the company that presents the webinar,” Cleary said.
After reviewing five years of data, he realized NSF’s problem wasn’t engagement. “We didn’t have an engagement problem. We had a content architecture problem,” he said.
Quality content was locked inside dense PowerPoint slides, and attendees who lost the thread for a minute or two eventually dropped off.
The Takeaway to Remember
Ask yourself: do your 2026 webinars look like they did in 2016? If they’re still mini university lectures, try cutting them to 30 minutes, splitting them into short modules, and starting each one with what your audience cares about most.
After all, nobody leaves a webinar remembering every minute. They remember the moments that made them think of their own projects. Build for those moments.
