Jon Stewart, host of The Daily Show, always said he was 'just a comedian.' But his 17-year run has proven that 'just a comedian' can change the world.

Later, Stewart quietly established a program to help veterans from the wars in Iraq and Afghanistan get into the TV business. He also made us laugh, a lot. VOA's Daniela Schrier has more on his legacy and his last show.
