What is Simulcast?
Simulcast - short for "simultaneous broadcast" - is the practice of streaming a live event to multiple platforms at the same time. For B2B marketers, this typically means broadcasting a webinar or live event to destinations like LinkedIn Live, YouTube Live, and a dedicated webinar platform such as Zoom, Goldcast, or ON24 in a single session.
The strategy has become increasingly common as B2B audiences fragment across platforms. Rather than asking your audience to come to one destination, simulcasting takes your content to every platform where your audience already spends time. Each platform also stores its own native recording, giving your content team multiple source files to repurpose after the event.
How simulcasting works
- Single production setup: You run one live session with your speakers, slides, and camera feeds - the same setup you would use for any webinar.
- Multistreaming layer: A tool like Restream, StreamYard, or your webinar platform's built-in integration sends the live feed to each destination platform simultaneously.
- Native recordings everywhere: Each platform records the stream natively. Your YouTube Live becomes a YouTube video, your LinkedIn Live stays as a LinkedIn post, and your webinar platform stores the full recording with attendee data.
- Post-event repurposing: You now have anchor content on multiple platforms, ready to be clipped, repurposed, and distributed.
Why Simulcast Matters for B2B Marketers in 2026
Live webinar attendance rates have held steady at 40-50% of registrants for years. Simulcasting addresses this by meeting audiences on platforms they already use - without requiring registration.
Problems simulcasting solves
- Audience fragmentation: Your ICP is not on one platform. Decision-makers might prefer LinkedIn, while technical buyers watch YouTube. Simulcasting reaches both groups from a single event without doubling production effort.
- Registration friction: Many potential viewers skip webinars because they don't want to fill out a registration form. Simulcasting to open platforms like YouTube Live and LinkedIn Live removes that barrier, expanding your total live viewership.
- Limited repurposing source material: A single Zoom recording gives you one file to work with. A simulcast gives you native recordings on YouTube, LinkedIn, and your webinar tool - each with its own reach and engagement data.
- Low post-event ROI: Events that only generate value during the live session waste most of their investment. Simulcasting creates on-demand assets on every platform automatically, extending the content lifecycle for weeks or months.
Real-World Examples
Product launch simulcast
A B2B SaaS company launches a new feature with a 30-minute live demo. They simulcast to Zoom Webinars (for registered leads with follow-up data), LinkedIn Live (for organic reach to their company followers), and YouTube Live (for SEO and discoverability). The Zoom recording feeds their nurture sequence. The YouTube recording ranks for the feature name within weeks. The LinkedIn recording gets clipped into short-form video highlights. One event, three platforms, three separate content pipelines.
Weekly thought leadership series
A demand gen team runs a weekly 20-minute live show with rotating industry guests. They simulcast to LinkedIn Live and YouTube, keeping production lightweight with StreamYard. Each week's recording produces 4-6 video clips, a blog post recap, and a batch of social posts - fueling a content calendar that runs itself.
Agency multi-client event day
A marketing agency runs quarterly "industry day" events for multiple clients. Each client's session is simulcast to the client's LinkedIn page and YouTube channel while the agency captures the Zoom recording for repurposing. After the event, the agency delivers a full content package from each session - clips, audiograms, quote cards, and show notes - all from the single simulcast recording.

Simulcast vs Similar Concepts
| Concept | What it means | How it differs |
|---|---|---|
| Simulcast | Streaming live to multiple platforms at the same time | Real-time, one production session reaches many destinations |
| Cross-Posting | Publishing the same content on multiple platforms after creation | Post-production; happens after the content is recorded, not during |
| Multi-Channel Distribution | Distributing content across multiple channels in any format | Broader strategy; simulcasting is one tactic within multi-channel distribution |
| Recording Platform | The tool used to capture and host the webinar recording | A single capture point; simulcasting sends the stream to multiple recording platforms |
Frequently Asked Questions
Common simulcast destinations for B2B webinars include LinkedIn Live, YouTube Live, Facebook Live, X (formerly Twitter), and dedicated webinar platforms like Zoom Webinars, Goldcast, and ON24. Many teams use a multistreaming service like Restream or StreamYard to send the feed to multiple destinations from a single production setup.
Not necessarily. Modern simulcast tools re-encode the stream for each destination platform at that platform's recommended bitrate and resolution. As long as your source stream is high quality (1080p, stable internet connection with at least 10 Mbps upload), each platform will receive a quality feed. The main risk is bandwidth - if your upload speed cannot support multiple outgoing streams, quality may drop. A dedicated multistreaming service handles the re-encoding server-side so your local machine only sends one stream.
No. Simulcasting happens in real time - you stream live to multiple platforms simultaneously. Cross-posting happens after the fact - you take a finished piece of content and publish it on multiple platforms. A webinar can be simulcast live and then the recording can be cross-posted later. Both strategies increase reach, but they serve different parts of the content lifecycle.
Simulcasting creates native recordings on each platform automatically. A YouTube Live stream becomes a YouTube video. A LinkedIn Live becomes a LinkedIn video post. Each recording already lives where its audience is, making it easier to repurpose into platform-specific short-form clips, blog posts, and social content. You also get separate analytics per platform, helping you understand which audience engaged most with the content.
No special hardware is required. Most simulcasting is done through software-based multistreaming tools that connect to your existing camera, microphone, and webinar setup. Services like Restream and StreamYard work entirely in the browser. If you already run webinars on Zoom or a similar platform, adding simulcast destinations typically takes just a few minutes of setup.
