Broadcasts go everywhere within a range determined by the sender.

Broadcasting is deprecated and unliikely to go beyond the nearest router.

Multicasts go everywhere where receivers have declared they are present.

Multicast can be implemented beyond routers in a WAN which you control but ISP routers generally don't support it.

You could also say they diff by topology.
