Since the server is serving exactly same data to multiple clients, does it send multiple copies of same packets with different destination addresses or does it send a single copy of a packet with a list of destination addresses?
If the commonly used protocols doesn't support this, are there any not so widely used options?
There is multicast, where clients can register "I'd like a copy of all packets to $address please", but it doesn't work on public internet. It's used by some providers for TV streaming inside their networks though.
There's also peer-to-peer approaches, where clients share the data they receive with other clients, similar to Bittorrent.
The most common approach is individual streams from the servers to the clients though.

This is how live-streaming on YouTube or twitch.tv works.
