the.com/presenter

means A person who hosts, introduces, or delivers content to an audience — on TV, radio, at an event, or in a meeting.

from From 'present,' rooted in Latin praesentare, 'to place before, show, exhibit' — itself from praesens, 'being at hand, in front.' The word walked a long road from 'physically put in front of someone' to 'formally give' (as in presenting an award) to the modern sense of the person who stands in front of a camera or audience doing the showing. The broadcasting use — someone who 'presents' a program — is a fairly modern narrowing of that older, broader sense of presenting as offering something up for others to see.
