Virtual Event Streaming and Webcasting: A Guide for Organizations

Virtual event streaming, often called webcasting, is the live broadcast of an event, a conference, town hall, product launch, or webinar, to an online audience watching from anywhere. A hybrid event does the same while an in-person audience is also present. The goal is to reach people who cannot be in the room with a reliable, professional live experience, and to keep the recording working afterward. It is a large and growing field, with the virtual events market projected to grow from about $145 billion in 2026 to $472.9 billion by 2033. Lightcast gives organizations a branded platform to stream live events reliably to Roku, Fire TV, Apple TV, iOS, Android, and web from one CMS across 70,000+ global CDN nodes, with automatic conversion to on-demand, serving 5,000+ organizations.

A virtual event is a live performance with no second take. The content can be excellent, but if the stream stutters at the keynote, that is what people remember. Getting the delivery right is most of the job.

What is virtual event streaming and webcasting?

Virtual event streaming is broadcasting a live event over the internet so a remote audience can watch in real time, on their own devices. Webcasting is the same idea, often used for the more formal or one-to-many events organizations run, like an annual meeting or an investor briefing. Both deliver a scheduled live experience to people who are not in the room, and both usually leave behind a recording for those who could not attend live. For the live foundation, see our pillar on live video broadcasting for content publishers.

What kinds of events do organizations stream?

A wide range, and most organizations stream more than they expect once they start. Conferences and summits reach attendees who cannot travel. Town halls and all-hands bring a distributed workforce together. Product launches and announcements go to customers and partners as a branded moment. Annual meetings, investor briefings, and shareholder events reach stakeholders wherever they are. Webinars, training sessions, and panels run throughout the year. Each is a live moment people may need to see now, and a recording they will reference later, which is why running the live event and its on-demand version from one place keeps the whole thing manageable. For the recording side, see our guide to live-to-VOD.

What makes a virtual event stream succeed?

Reliability, above everything. A virtual event happens once, often with the whole audience arriving in the same few minutes, which is exactly the combination that overwhelms weak delivery. The stream has to hold up at the start time and through the keynote, which is a function of the delivery network behind it. Reach matters too, since attendees watch on laptops, phones, and connected TVs, and the experience should be smooth on all of them. Get those right and the content can do its job. For why delivery is the deciding factor, see our guide on what makes streaming reliable.

Virtual vs hybrid events: what is the difference?

A virtual event is online only, with everyone attending remotely. A hybrid event has both an in-person audience and an online one at the same time, so the stream has to serve remote attendees as well as the room. Hybrid has become the default for many organizations because it captures both audiences at once, the people who value being there and the much larger group who can only join online. The streaming requirements are the same in spirit, reliable delivery and broad device reach, with the added need to make the remote experience feel first-class rather than an afterthought.

What should you look for in a webcast platform?

A few things matter most.

Reliable delivery at scale. The platform has to hold up when the whole audience arrives at once, across a real content delivery network.

Reach on every device. Attendees should be able to watch on laptops, phones, and connected TVs without friction.

Automatic recording. The event should convert to an on-demand version automatically, so the people who missed it still get it. See our guide to the best on-demand video platforms.

Your brand and your data. The event should run under your brand, with the attendee data staying with you.
