Webcast vs webinar: what is the difference?
A webinar is a seminar on the web: a presenter, slides and an audience expected to take part. A webcast is a broadcast on the web: a produced programme for an audience that can run into the thousands. The two overlap. The right choice depends on how many people watch and how much the moment matters.
Webcast vs webinar side by side.
Both put a presenter in front of an online audience. They differ in what they are built for.
| Webinar | Webcast | |
|---|---|---|
| Built for | Conversation | Reach |
| Audience size | Tens to a few hundred | Hundreds to many thousands |
| Who is on camera | Presenters, sometimes attendees | Only the stage |
| Production | A webcam and the platform's layout | Cameras, a vision mixer, graphics and a crew |
| Audience role | Asks, votes, chats, sometimes speaks | Watches, asks and votes through a moderator |
| Typical use | Training, product demos, lead generation | Town halls, AGMs, conferences, launches |
| Where it plays | Inside the webinar tool | A branded page, a social stream, or both |
What a webinar is good at.
A webinar is a meeting organised for an audience. It runs inside a tool such as Zoom Webinars, Microsoft Teams webinars or a dedicated webinar platform. The presenter shares slides, attendees register, and the tool handles questions, polls and the recording.
Webinars work when the audience is small enough to talk to. A product demo for sixty prospects. A training session for one department. A panel of three experts taking questions from a few hundred people. The value is in the conversation, and the tool is built for it.
Webinars struggle with scale and polish. The layout belongs to the platform, not to you. The picture is a webcam. If the presenter's home connection fails, the session stops.
What a webcast is good at.
A webcast is a broadcast. The stage is produced like television: several cameras, a vision mixer, graphics, clean sound, and a crew watching every link. The audience watches a finished programme on a branded page or a social platform.
Webcasts work when the audience is large or the moment matters. A leader speaking to every office. An AGM with shareholders watching. A conference stage going out live. The value is in the reach and the certainty, and the production is built for it.
A webcast audience can still take part. Questions and polls travel to a moderator, who passes the best to the stage. The difference is that nobody in the audience can break the show. More in our guide: what is a webcast.
Which does your event need?
Three honest answers. Most events fit one of them.
Choose a webinar
Choose a webcast
Choose both
If you already run everything in Microsoft Teams, our five-question test in webcast vs Microsoft Teams tells you when to step up.
The produced webinar.
The line between the two is blurry. A webinar can be produced: a real camera, a studio, a moderator and branded graphics, carried into the webinar tool. That is often the right answer for a marketing series, where the registration and follow-up in the tool matter, but the picture has to look like your brand.
Our work for the Global Youth Coalition is an example of one standard across a series. We co-produced the Reeforesting for Peace series for the Global Youth Coalition: seven sessions, four UN languages, one production standard.
We produce both formats. See webinar production and webcasting services.
What is a webcast? A guide from the control room.
A webcast is a video broadcast over the internet to an audience that watches rather than joins. What it means, how a professional webcast is produced, and what drives the cost.

Microsoft Teams is right for most internal video. For large, external or high-stakes events, a produced webcast is the better answer. Here is where the line sits.
Read the articleThe real ROI of producing your webinar properly.
Most webinar ROI calculations miss half the math. The cost side is obvious. The returns are what marketing teams consistently underprice: pipeline from attendance data, content you re-cut for months, and the second event that converts better because you know who to invite.
Read the articleQuestions we get asked.
Is a webinar the same as a webcast?
No. A webinar is built for conversation with a smaller audience. A webcast is built for reach, with a produced programme. Many events mix the two.
Which is better for a large audience?
A webcast. Webinar tools have attendance limits and a meeting layout. A webcast is delivered through a content delivery network and scales with the audience.
Can webcast viewers ask questions?
Yes. Questions and polls travel to a moderator, who sends the best to the stage. Viewers need no camera and no microphone.
Is a webcast more expensive than a webinar?
Usually, because it has cameras, a crew and a control room. It also takes the risk of failure away from you. The cost depends on the scope, not the label.
What is the difference between a webcast and a podcast?
A webcast is video, usually watched live. A podcast is audio, recorded, and listened to later.
