Can someone provide a few examples of NBC, CBS, and ABC showing a clear liberal bias during their evening news broadcasts? 
HAHHAHAHAHAH!!
You are an idiot.
I will entertain your moronic existence just this one time. Here are comments by people who worked at those companies. Yeah, I know libtards like you will say that these are former disgruntled workers. But, instead of deflecting, why don't you try to prove them wrong?

CBS's bogus 60 Minutes National Guard story] had been about John Kerry?"
— Former 60 Minutes Executive Producer Don Hewitt at a January 10, 2005 meeting at CBS, as quoted by Chris Matthews later that day on MSNBC's Hardball.
"Personally, I have a great affection for CBS News....But I stopped watching it some time ago.
The unremitting liberal orientation finally became too much for me. I still check in, but less and less frequently."
— Former CBS News President Van Gordon Sauter in an op-ed published January 13, 2005 in the Los Angeles Times.
"I don't know if it's 95 percent...[but] there are enough [liberals] in the old media, not just in ABC, but in old media generally, that it tilts the coverage quite frequently, in many issues, in a liberal direction....It's an endemic problem. And again, it's the reason why for 40 years, conservatives have rightly felt that we did not give them a fair shake."

"From a reporter's point of view, it's almost hard to remain objective because it's infectious, the energy, I think. It sort of goes against your core to say that as a reporter, but the crowds have gotten so much bigger, his energy has gotten stronger. He feeds off that."
— NBC reporter Lee Cowan in an MSNBC.com video about the Obama campaign posted January 7, 2008.
“You know, it’s fairly well discussed inside CBS News that there are some managers recently who have been so ideologically entrenched that there is a feeling and discussion that some of them, certainly not all of them, have a difficult time viewing a story that may reflect negatively upon government or the administration as a story of value....They never mind the stories that seem to, for example — and I did plenty of them — go against the grain of the Republican Party....I didn’t sense any resistance in doing stories that were perceived to be negative to the Bush administration — by anybody, ever. I have done stories that I perceived were not received well because people thought they would reflect poorly upon this [the Obama] administration.”
— Former CBS News investigative correspondent Sharyl Attkisson on CNN’s Reliable Sources, April 20, 2014.
