A 24-Hour Telethon is a fundraising event that lasts for a full day, typically broadcast on television or online. During this time, various entertainers, celebrities, and volunteers come together to raise money for a specific cause, such as medical research or disaster relief. Viewers are encouraged to donate while enjoying performances, interviews, and special segments. These telethons often feature emotional stories and testimonials from those affected by the cause, aiming to inspire generosity. Popular examples include the Jerry Lewis MDA Telethon and the St. Jude Children's Research Hospital Telethon. The event fosters community involvement and highlights the importance of charitable giving.
