Webinar

Origin & evolution

The word "webinar" fuses "web" and "seminar". A trademark for the term was filed in 1998 by Eric R. Korb, though it proved hard to defend and the word soon passed into common use. The format grew out of web-conferencing technology that matured through the late 1990s and early 2000s, as bandwidth and screen-sharing made it possible to run a slide presentation and a live audience over the open internet.

Two refinements shaped how webinars are used now. The first is the live-versus-on-demand split. A live webinar trades on scarcity and real-time interaction, the questions and the sense of an event. An on-demand recording trades that energy for reach, available to anyone who registers later, which is why most programmes now run both from a single production. The second is repurposing. A single recorded session becomes a back catalogue: clips, a blog write-up, a gated asset, an email series, so the cost of producing one event is spread across many pieces of content.

The attendance economics are sobering and well documented. Across large benchmark datasets, roughly 40 to 50 percent of registrants attend live, with the average sitting near half. Half the people who said yes do not turn up at the appointed hour. That single fact promotes the on-demand recording to the larger half of the audience, and it makes the registration list, more than the live room, the asset a demand-generation team actually values.

How it works in practice

A B2B analytics company runs a webinar titled "How three teams cut reporting time by 60 percent". Four hundred people register. By the benchmark, around 190 attend live; the rest are sent the recording. The session is built as a teardown of real workflows with the product appearing only where it genuinely does the work, so the teaching holds and the average watch time stays high.

The event does not end when the stream stops. The recording is gated behind a form and keeps generating registrations for months. The strongest fifteen minutes are cut into three short clips for social, and the transcript is rewritten into a how-to article that ranks in search. One hour of live presentation becomes a content engine, and the registration list, qualified by topic, flows to sales as warm leads. The webinar earned its keep less as a broadcast and more as a source of durable assets.

Webinar vs. its neighbours

• Content piece🗒️Content PieceContent & KnowledgeA piece of content (article, video, etc.)View reference → is the durable artefact: the clip, the article, the gated recording. A webinar is a live event that produces content pieces; the content piece is what outlives the hour. The graph models this with webinar_generates_content_pieceWebinargeneratesContent Piececross-domain.
• Event is the broader category of organised gatherings, including conferences, workshops, and meetups, online or in person. A webinar is the specific online, presentation-shaped event, lighter to produce and easier to record and reuse than its physical cousins.
• Education program🏫Education ProgramCustomer EducationA customer education programView reference → is the structured curriculum a webinar can be one delivery of. The programme is the syllabus and the through-line; the webinar is one session it presents, which is exactly how the graph connects them.

In the graph

In the Unified Product Graph, a webinar sits in the education domain as a delivery format that doubles as a demand-generation surface. An education programme presents through it via education_program_presents_via_webinarEducation Programpresents viaWebinarhierarchy, placing the webinar as one act of teaching inside a larger curriculum. Its second life is captured by webinar_generates_content_pieceWebinargeneratesContent Piececross-domain, which models the repurposing that gives a one-off event its lasting value. That pair of edges encodes the format's real shape: a scheduled session upstream, a fan-out of reusable content downstream, so the graph can trace a single hour of presentation to every asset and audience it later produced.
