A Telethon is a televised fundraising event that typically lasts several hours or even days. It features various entertainment segments, including music performances, celebrity appearances, and live auctions, all aimed at raising money for a specific cause or charity. Viewers are encouraged to donate through phone calls, online platforms, or text messages during the broadcast. These events often support organizations like children's hospitals, disaster relief funds, or medical research. Telethons have been popularized by figures such as Jerry Lewis, who hosted the annual Muscular Dystrophy Association Telethon for decades, raising millions for research and support services.
