What Is a Webinar? 6 Definitions That Explain Everything
Webinars have settled firmly into how we work and learn. Some people host them regularly, others drop in as attendees now and then. But if someone asked you point-blank what a webinar is, could you answer in one clear sentence? We gathered six definitions, and each one reveals a different side of the format.

📌 Key Insights

Instead of hunting for one “perfect” definition, let’s look at several – from dictionaries and from the industry. Each one adds a single important piece. Together, they build a complete picture of what a webinar really is.
How Do Language Dictionaries Define a Webinar?
Dictionaries describe a webinar simply: a seminar conducted over the internet. That’s a solid starting point, because it flags two things at once – the format (a seminar, meaning a session built around a specific topic) and the medium (the web). Let’s see how different sources build on that.
What Do Oxford and Collins Say About Internet and Interaction?
The Oxford Dictionary defines a webinar in the fewest words possible: “a seminar conducted over the internet.” It sounds obvious, but it points straight at the foundation – without a stable connection, you can’t host or attend the event. A webinar platform lets you bring people from different cities and countries into one room, which is exactly why it pays to check that your connection works properly before your first webinar.
Collins adds one crucial word: interactive. And that’s what separates a webinar from an ordinary recording. You don’t sit alone in front of a camera and microphone, talking into the void – and attendees don’t just watch passively. Throughout the event, you exchange questions, comments, and reactions. That back-and-forth is the heart of the format.
Why Is Interactivity the Most Important Feature of a Webinar?
Because without it, a webinar turns into a plain video. Merriam-Webster describes a webinar as “a live online educational presentation during which participating viewers can submit questions and comments.” That definition shifts the weight from the host onto the relationship between the host and the audience.
In practice, it means you can genuinely talk with your audience. When a question pops into someone’s head, they ask it in the chat right away – no waiting. At the end, you can open a Q&A session, clear up doubts, and fill in details. Then you can ask attendees to complete a short survey: did the event meet their expectations, what would they like to hear about next time. That closes the loop and hands you material for your next event.
The tools that make this possible are now standard on any good webinar platform. In ClickMeeting you have chat, Q&A sessions, polls and tests, plus CTA buttons attendees can click during the broadcast. These aren’t extras – they are exactly the interaction every definition keeps pointing to.

Is a Webinar Primarily an Educational Tool?
To a large extent, yes – and the Cambridge Dictionary underlines it, defining a webinar as “an occasion when a group of people go on the internet at the same time to study and discuss something.” Learning and discussing a topic together are the two pillars most webinars stand on.
You can step into the expert’s role and share knowledge on a topic your audience cares about. You can run a video-tutorial webinar and show, step by step, how to build, cook, fix, or choose something. Or you can simply pass on tips from your own experience. Educational formats are, in fact, one of the most common reasons companies reach for webinars – from internal training to paid courses for external clients.
That this scales is clear from Centrum Verte, whose HR training series gathered more than 30,000 unique attendees, with a single event drawing as many as 6,500 people – and a record 81,018 leads collected in one year. An educational webinar, then, is often the most effective lead-generation tool you have.

“ People often ask us for a definition of a webinar, and I always answer the same way: the definition matters less than what actually happens during the event. We see a very clear pattern in the data – events where the host truly talks with attendees, asks questions, and reacts to the chat have higher attendance and longer average watch time. Streaming audio and video is only half the job. That’s why I encourage people not to treat chat, polls, or Q&A as add-ons, but as the main reason someone chooses a live format over simply watching a recording.

A Webinar as a Video Conference – How Much Can You Show on Screen?
Quite a lot – and that’s exactly what the LifeWire definition focuses on. It describes a webinar as “a live web-based video conference” that connects the host to an audience from all over the world, adding that the host can appear on camera, switch to their computer screen for slideshows or demonstrations, and even invite guests from other locations to co-host.
Speaking of tools – you have plenty at hand when you deliver a lecture online. You can turn on your camera so the audience sees you throughout the event. You can run a presentation, share your screen, or use a virtual whiteboard to show how an app works. And if you need a helping hand and your platform allows it – ClickMeeting does – you can invite a second host to run the webinar alongside you.
In ClickMeeting you can display up to 8 camera streams at once, stream live to YouTube and Facebook, and use breakout rooms for work in smaller groups. That turns a simple video conference into a fully-fledged event.

What Does It Mean That a Webinar Happens in Real Time?
It means that everything you do during the event happens here and now – and that’s the foundation of the Webopedia definition. It describes a webinar as a presentation, lecture, workshop, or seminar transmitted over the web using video conferencing software, whose key feature is the ability to give, receive, and discuss information in real time.
This is the last, but by no means least important, feature. Interaction, knowledge sharing, asking and answering questions – all of it happens live, as if you were all sitting together in one room. Because of that, you react instantly: to every question, every comment, every doubt. Attendees don’t have to wait for your help, and you don’t have to guess what they need – you simply ask and listen.
It’s worth adding that “live” doesn’t rule out life after the event. You can later share the recording with people who couldn’t join, or sell it as a separate product. The real-time element builds engagement during the event, and the recording extends its value for weeks and months.
One Definition or Six? How to Put Them Together
As you can see, if we tried to write one precise and exhaustive definition of a webinar, it would turn into a fairly long piece of text. Each definition above focuses on a different feature – the internet, interaction, education, video conferencing, and real time – and only together do they give the full picture.
If we had to compress them into a single sentence, it would read roughly like this: a webinar is an interactive educational event held live over the internet, in which the host and attendees exchange knowledge and questions in real time. But you only discover its real value once you run your first event and see how these features work in practice.
Frequently Asked Questions
Here are answers to the questions that come up most often when people first encounter webinars.
What is a webinar in the simplest terms?
A webinar is a seminar or presentation held live over the internet, where attendees can interact with the host – asking questions, commenting, and taking part in polls. It combines online reach with direct, two-way communication.
How is a webinar different from a regular online meeting?
An online meeting is usually a conversation among a small group where everyone is an equal participant. A webinar has a clear split between the host (or hosts) and the audience, is planned around a specific topic, and often serves hundreds or thousands of people at once.
Do you need to install anything to attend a webinar?
On modern platforms – no. In ClickMeeting the webinar runs in the browser, so attendees join with a single click on a link, without downloading or installing any software. That lowers the barrier to entry and lifts attendance.
How many people can attend a webinar?
It depends on the platform and plan. ClickMeeting supports events for more than 10,000 attendees. For comparison, the State of Online Events 2025 report shows the average online event draws 75 people – so you have plenty of room to grow.
How long should a webinar last?
There’s no single right length, but the data gives a useful benchmark. The average online event runs 106 minutes – enough to develop a topic and leave time for questions. Holding attention is what matters, so it’s worth alternating presentation with interaction.
Can you make money from a webinar?
Yes. You can sell tickets or recordings using payment integrations (Stripe, PayU, PayPal). According to SOE 2025, the average revenue from a single paid webinar is around €1,020, and the record for one event reached roughly €36,000.
Which features are essential for running a good webinar?
The basics are chat, Q&A sessions, polls, plus screen and presentation sharing. Automated email reminders, recording, and attendance statistics are also invaluable. These tools turn passive watching into real interaction.
Are webinars suitable for internal company training?
Absolutely. They work well for onboarding, product training, and meetings for distributed teams. Recordings and certificates let you document participation, and the no-install access makes it easy for employees to join regardless of location.
Are webinars safe for attendees’ data?
It depends on the provider. ClickMeeting hosts data in Europe and meets GDPR requirements, which is a meaningful advantage over US-based platforms. For companies processing attendees’ personal data, that’s often a decisive factor in choosing a tool.
How do you start running webinars with ClickMeeting?
The easiest way is a free trial account, which runs for 14 days and requires no credit card. You create an account, build a registration page, invite attendees, and run your first event from the browser. If you’d rather see the platform live, you can also book a short demo.
