Yes, but not the way you're asking.

Multicast to end user workstations and between ISP's is probably dead
and will never return.

Multicast used in private networks, including to distribute programming
to set top boxes is alive and well, often hidden in view but in use by
millions.

It's not just live TV, in the sense of sports.  Many businesses leave on
their favorite news channel 24x7x365, people still tune into topical
shows (evening news, the late show) on schedules, etc.  And some of them
also do things like push software and guide data using multicast.
