Fake news is nothing new. Its impact has waxed and waned through American history. But there was a golden age of "yellow journalism," back in the 1890s, when fake news helped start a war.
Yellow journalism has been defined as any journalism that treats news in an unprofessional or unethical manner.
The term was coined in the 1890s to describe the ferocious circulation war between William Randolph Hearst's New York Journal and the New York World, owned by Joseph Pulitzer.
