> Sanders’ media coverage during the pre-primary period was a sore spot with his followers, who complained the media was biased against his candidacy. In relative terms at least, their complaint lacks substance. Among candidates in recent decades who entered the campaign with no money, no organization, and no national following, Sanders fared better than nearly all of them. Sanders’ initial low poll numbers marked him as less newsworthy than Clinton but, as he gained strength, the news tilted in his favor.
And for Trump:
> By our estimate, Trump’s coverage in the eight news outlets in our study was worth roughly $55 million. Trump reaped $16 million in ad-equivalent space in The New York Times alone, which was more than he spent on actual ad buys in all media during all of 2015. In our eight outlets, the ad-equivalent value of Trump’s coverage was more than one-and-a-half times the ad-equivalent value of Bush, Rubio, and Cruz’s coverage, more than twice that of Carson’s, and more than three times that of Kasich’s. Moreover, our analysis greatly underestimates the ad-equivalent value of Trump’s exposure in that it’s based on only eight media outlets, whereas the whole of the media world was highlighting his candidacy. Senator Cruz might well be correct in claiming that Trump’s media coverage was worth the equivalent of $2 billion in ad buys.
It's an interesting read.
