Synonym discussion
Sense: noun/1
Live streaming refers specifically to video or audio sent over the internet in real time. Webcast is a more formal term that usually describes a professionally produced online broadcast, such as a company's annual meeting or a conference keynote. Broadcast has a much wider scope — it covers TV, radio, and any transmission to an audience, regardless of medium or delay. Livestream is a modern one-word spelling variant of live streaming and is interchangeable in most contexts. For example, a teenager talking to followers on a game platform does live streaming or a livestream, not a webcast; a news organisation transmitting a press conference might call it a webcast or a live broadcast depending on how formal they want to sound.

Etymology
The term combines live (from Old English lif, meaning 'living, alive' — used since the early 1900s to describe real-time radio and TV performance) with streaming (from Old English streám, adopted in computing during the 1990s to describe continuous transmission of data). The compound live streaming emerged with broadband internet in the early 2000s and became common as video-sharing platforms grew after 2010.
