Jay Leno believes late-night talk shows are alienating viewers with their political stances. The 75-year-old comic - who hosted The Tonight Show from 1992 until 2009 and again from 2010 to 2014 - was able to appeal to a "whole audience" by staying neutral with his humour and thinks hosts now have to accept they'll never gain universal appeal because they have to offer their opinions on the state of the world.
