I’ll leave an excerpt here. Well-written, well-put piece :
“As of 2013, The Daily Show was bringing in  approximately 2 million nightly viewers. And according to an exhaustive Pew Survey  from 2012, 39 percent of The Daily Show’s regular viewers are between the ages of 18 and 29. That means that approximately 780,000 millennials are regular Daily Showwatchers. In the United States, there are 53 million  people between the ages of 18 and 29. That means that a whopping 1.5 percent of millennials watch the Daily Show regularly! Let’s be generous and assume that, say, 5 million people watch The Daily Show even occasionally. That would still mean a paltry 1.95 million out of 53 million millennials are Stewart fans.
That’s not all. According to Bill Carter , then of the New York Times, the average Daily Show viewer is 41 years old. Considering other cable shows alone, It’s Always Sunny in Philadelphia, Archer,American Horror Story, and Louie all have significantly younger audiences  than does Stewart. And here’s my favorite nugget: 9 percent of the regular viewers of the nightly evening news – long derided as the news source of the geriatric set – are between the ages of 18 and 29. About 22 million people watch the nightly news. Thus, nearly 2 million millennials are regular viewers of the nightly evening news. That’s right: more than twice as many millennials watch Brian Williams, Scott Pelley, et al, than watch The Daily Show.”
