Streaming, Broadcasting or Webcasting: What Is the Difference?

These get used interchangeably in briefs and tenders, which causes problems when suppliers price against different assumptions.

Live streaming

Sending video over the internet as it happens, to anyone with the link. Usually a public or semi-public platform: YouTube, a website player, a social channel.

Implies scale is handled by the platform and access is open or lightly gated.

Broadcasting

Strictly, transmission over the air or via satellite or cable to a broadcaster. In practice people now use it loosely to mean any high-production-value live output.

If it appears in a tender, worth clarifying whether they mean television delivery, which has technical standards and compliance requirements attached, or whether they mean a good-looking stream.

Webcasting

Usually a corporate or institutional stream with controlled access: registration, a login, a defined audience, often with analytics on who watched what. AGMs, investor updates and internal all-hands.

The distinguishing features are access control and reporting rather than production quality.

Why the distinction matters commercially

A brief saying "we need a broadcast" might mean television-standard delivery, or might mean two cameras and a lower third. The gap between those two is substantial.

A brief saying "webcast" implies access control and reporting that a public stream does not need, and those cost money.

A brief saying "live stream" says nothing at all about production values, which is why quotes against it vary so widely.

The clearer way to write a brief

Say what the audience is, how many, whether access is controlled, what production values you expect, and what you want afterwards. Those five answers get you comparable quotes. The category noun does not.
