IP multicast is used quite extensively for streaming video. Mostly in combined voice/video/data networks for IPTV (think hotel rooms, but also network service providers), as well for stuff like e.g. security cameras.
On the public Internet it's still virtually unheard-of afaik, and I expect it to remain that way indefinitely.
(I used to work on IP multicast support for network switches.)
