TV presenters

Silvio Santos: one of the most famous Brazilian comperes!





It will depend on the sort of show...

Variety show - presenter or compere.
News broadcast - presenter, newsreader, link-man
Chat show - host, presenter
Quiz show - host, presenter, quiz-master



Of course, when the show mixes these genres, the name of the front-man is flexible; but - for example - you'd be unlikely to have a compere on any sort of news-related show.
