Webcasting is formed from "web" (originating from Old English *webb*, meaning a woven fabric or network) and "casting" (from Old Norse *kasta*, meaning to throw). The term describes the act of broadcasting content over the internet, akin to throwing information across a network.
Think of a 'woven network' ('web') where information is 'thrown' ('casting') to viewers — that's what webcasting means.
