News Video on the web has become so big now that more and more people use the internet for everything including for news. According to Journalism.org news videos picked up around 2013. Since then more than six in ten U.S. adults now watch videos online instead of anywhere else! Roughly about 36% of U.S adults watch the news on video on the web, 27% don't watch news videos and 63% watch videos online period according to Pew Research Center.
Although Videos online have become very popular, according to sources it doesn't look like it's something that's going to last because it's simply very costly and "the payoff is not clear". The younger generation seems to be the biggest consumers of online videos, so in my opinion it could possibly be major form of news in the near future.
