The podcast revolution The podcast revolution is erupting all over the world—and seemingly all at once. Why is it getting so popular? The technology is simple to master and podcasting software is inexpensive, sometimes even free. Two Chinese students are receiving international fame as millions of people around the world watch them podcast from their dormitory. They are called the Back Dormitory Boys, and they specialize in mouthing Backstreet Boys’ songs. Although most people in China don’t have iPods, podcasting is sweeping the country.
