The 24 hr news cycle is a competitive business.  Fox, CNN, MSNBC, etc. are for-profit businesses that compete with each other for advertising dollars.  The "news" network with the most viewers attracts the most ad bucks.  Trump crazy sound bites, 3-5 word sentences about himself, beautiful wife, orange suntan and hair comb over are perfect for the nature of the TV news channels.  I'm not making excuses for the media, but Trumpiness attracts viewers like a train wreck and sells ads.  Most people seem to like the echo chamber of what they see on cable news and what they believed anyway. It reconfirms their bias or they would not be watching this dumpster fire.
