Interestingly multicast is used extensively by exchanges to distribute trading data to participants. I think it's the primary commercial usage outside of some IoT things.

In Japan IPv6 multicast is used for IPTV services[0] over GPON, competing with satellite TV (cable TV is not nearly as widely deployed as fiber). I imagine it's similar anywhere else that offers linear IPTV over fiber.
To use it you need to make sure your router supports MLD snooping

Triple-play networks can use it to distribute TV.
It's used within at least one streaming TV company to get the streams from the identical-to-pirate satellite decoder boxes to the ffmpeg encoder boxes.
I've worked with a few video headends, it's all multicast all around inside the core.
Even extremely small users are leveraging systems like the DISH Smartbox to distribute satellite TV inside their properties as multicast IPTV.

Alternatively, slightly larger operators use Smartboxes and feed the multicast into their own repackaging and DRM to kick out to their end-users as a streaming TV product. We also used lots of HDHomeRuns to provide local television channel insertion where it was required on top of it.
I will say - I LOVE the Smartbox platform and how far it's transformed television distribution. We've gone from 3-4 full 40U racks all wired up with individual satellite boxes down to a very, very elegant power-sipping 3RU box that can pull in 192 channels and IPTV from the Web.
