A Host (Presenter) is an individual responsible for guiding and facilitating a program, event, or show. They engage the audience, introduce topics or guests, and ensure the smooth flow of the presentation. Hosts can be found in various settings, including television shows, podcasts, and live events. In addition to their speaking skills, hosts often prepare by researching content and practicing their delivery. They may also interact with the audience, answer questions, and manage time effectively. Successful hosts, like Ellen DeGeneres or Jimmy Fallon, create an inviting atmosphere that keeps viewers entertained and informed.
