The fact that FNC found slightly more attractive news readers than the other networks in no way means that they started the trend.
Newsreaders have been vacuous, barely sentient beings throughout my lifetime, which includes [among many empty-headed morons] Walter Cronkite. He was picked for his serious demeanor, a stentorian voice, and the fact that he was one of Murrow's Boys which gave him instant credibility and insured he was a leftist.
ALL television "journalists" are selected for their Q and image projection, and they always have been.
Dead on.
