Late night TV has always been very competitive. The shows that occupy the time slots after local news broadcasts can be quite lucrative for networks. Things have not changed in terms of competitiveness since the days when Johnny Carson was in his prime. However, what has changed is the fact that technology is now playing a huge role in what late night shows people watch. In the old days, a person would need to record a show on their VCR if he or she was unable to watch it live. Otherwise, they would not be able to watch the show. However, video sites like YouTube have completely changed the game. It has become increasingly common for people to watch clips from their favorite late night shows online the following morning.
Advertisers have noticed this trend and are taking advantage of it in a big way. In fact, online ad sales are now surpassing those for TV where late night shows are concerned. The simple fact is that many people do not have daily schedules that allow them to stay up late enough to watch these shows when they are broadcast live. Therefore, it is much easier for them to watch what happened on Fallon, Corden, Kimmel or Conan when they are at work the next morning. The clips are available on YouTube for people to watch whenever it is convenient for them. Some of the more popular clips posted online by the late night shows have been viewed millions of times.
