Thesis: Ever since CNN introduced the world to the 24-hour news cycle it has changed the political world drastically. Politics has become strongly reliant on the 24-hour news cycle, in several ways. 

Some background knowledge just in case you need it:  America was introduced to the 24-hour news cycle by Ted Turner the founder of Cable News Network (CNN).
