Telethons are a popular way to raise funds for various organizations. They are typically televised events that feature live entertainment and calls to donate. However, there are several other terms that can be used to refer to these types of events. One synonym is a charity marathon, which suggests a long period of fundraising efforts. Another synonym is a telethonathon, which combines the words "telethon" and "marathon". Similarly, a telethon-a-thon emphasizes the endurance required of both the organizers and the donors. Other synonyms include giving days, pledge drives, and fundraising campaigns. Whatever the term used, the goal remains the same - to raise funds for a worthy cause.
