WNTH is known locally for " RadioThon " , their annual charity broadcast . The event , usually held on a Sunday in April or May , features on-air interviews with actors , musicians , politicians , and other people of interest from across the nation . All money raised goes to a charity selected by the WNTH Radio Board prior to the event . The event began in 2005 as a unique way to raise money for victims of the 2004 Indian Ocean earthquake and tsunami . However , the event was so successful in raising money that the WNTH Board of Directors decided to continue the tradition yearly . In recent years , the event has raised thousands for children 's oncology research and Kiva ( organization ) . The most exciting aspect of RadioThon is the variety of guests interviewed during the event . Guests have included Paul Rudd , Rod Blagojevich , and New Trier graduate Rainn Wilson
