It’s the end of an era at NBC as the network has announced that Bob Costas is stepping down as its primetime Olympics host. Starting with next year’s Winter Games in South Korea, NBC’s new Olympics host will be Mike Tirico, a former Monday Night Football play-by-play announcer and ESPN host who joined NBC Sports specifically for some kind of big opportunity like this. According to The Wrap, Tirico was also set to take on a full-time position on Sunday Night Football, but it’s unclear if that will happen along with his new Olympics gig.
