Game streaming explained: how live gaming broadcasts work

Chapter one: from a gaming PC to thousands of screens

A game stream starts on the streamer's own machine. Broadcasting software captures the game, adds a webcam, microphone and on-screen graphics, compresses the result into video and sends it to a streaming platform. The platform then copies that video and delivers it to every viewer, often at several quality levels so slower connections still work.

There is always a short delay between something happening on the streamer's screen and viewers seeing it. That delay is why a streamer can sometimes appear to answer chat a few seconds late. Some platforms let streamers reduce it for more immediate conversation, while big events sometimes add deliberate delay so that competitors cannot gain information by watching the broadcast.

Major esports events work the same way at a much larger scale, with production teams, observers controlling in-game cameras and commentators. How game streaming works explains each step.

Chapter two: clips, VODs and chat

Streaming has its own vocabulary:

• VOD (video on demand): a recording of a past stream that can be watched later.
• Clip: a short excerpt of a stream, usually made by viewers to share a highlight.
• Chat: the live text conversation running alongside the stream, managed by the streamer's moderators.
• Raid: when a streamer finishes and sends their audience to another channel.

Chat is what makes streaming feel different from television. It is also the part that needs the most care, especially for younger viewers. Most platforms let viewers hide chat entirely, filter certain words or watch a VOD later without chat at all. Streamers can restrict chat to followers or subscribers, slow it down so each person can only post every few seconds, and appoint trusted moderators to remove messages and time out anyone breaking the channel's rules. Clips, VODs and chat explained covers each feature, and our glossary has the rest of the jargon.

Chapter three: age rules on the main platforms

Each platform publishes its own age rules. On 3 November 2026 they said:

• Twitch: its services are not available to anyone under 13. Users aged 13 up to the age of majority may use it only under the supervision of a parent or legal guardian who agrees to Twitch's terms. Twitch also offers a Family Center for parents.
• YouTube: under-16s may take part in a live stream from an adult's account only if the adult is visibly present. Live streams showing under-16s without a visible adult may be removed or have chat disabled.
• Kick: its terms prohibit use by anyone under 13, or under the age of digital consent in their country, and require parental consent for under-18s.

In the UK, Ofcom's Protection of Children Codes under the Online Safety Act have applied since 25 July 2025, requiring services used by children to take practical safety measures. Streaming safety for teens turns these rules into practical steps.

Chapter four: watching events as they happen

Live streams are the main way to follow both esports and speedrunning. Big esports events stream free on official channels, with commentary in several languages. Charity speedrun marathons such as Games Done Quick run around the clock for a week, with commentators explaining each run.

Some events also welcome live audiences. VALORANT Masters London sold tickets for its run at the Copper Box Arena in June 2026, and the RLCS Club Championship Kick-Off plans a live audience there from 11 to 13 December 2026.

Watching esports and speedruns live covers finding schedules, time zones, VODs and what to expect at an arena.

Chapter five: streaming your own games

Plenty of viewers eventually want to try streaming themselves. The basics are simple: an account on a platform, free broadcasting software, a game and a reasonably stable internet connection. A microphone and webcam are optional; many streamers start with neither.

Before going live, it is worth deciding a few things in advance:

• What to share: keep your full name, school, location and anything visible in the background private.
• Who moderates chat: platforms offer word filters and moderator roles; switch them on before the first stream.
• When to stream: a regular, limited schedule is easier to manage than open-ended sessions.
• Platform rules: check the age rules above. For under-18s, a parent or guardian is involved under Twitch's and Kick's terms.

Speedrunners in particular often stream every attempt, because the recording doubles as evidence for leaderboards. How to start speedrunning covers recording for that purpose.
