During the primaries, the cable TV networks virtually handed a free microphone to Donald Trump, while giving other candidates a small fraction of his attention. By February, Trump had “earned” nearly $2 billion of free media, more than six times that of his closest Republican competitor, Ted Cruz, and almost nine times the next closest candidate, Jeb Bush.

The tens of millions of Americans who most often get their news from television, 57 percent of U.S. adults according to the Pew Research Center, had been fed a steady diet of Trump PR.

TV gave scant attention to the long history belying Trump’s claims that his personal successes would surely “Make America Great Again.” Instead, the all-Trump-all-the-time media attention permitted the presidential candidate to perpetuate the myth he had built as the savvy billionaire who would be America’s savior.

Millions of Republican voters fell for it. Even during Republican primary debates, many of the questions were Trump-centric, focusing on his statements and positions. While Trump sucked up air time, little was left for other candidates, a huge disadvantage in their efforts to connect with the American public.

As ratings soared, CBS CEO Les Moonves said of Trump’s dominance in the election coverage, “It may not be good for America, but it’s damn good for CBS.… The money’s rolling in and this is fun.”

Indeed, the Trump ratings boost has been manna for an industry that had been under assault from the internet, suffering years of shrinking audience, a rapid aging of viewer demographics and declines in profitability.

So, why shouldn’t TV executives be celebrating? Because the news business is about more than making money, more important things like ensuring the public is well informed. An informed electorate is crucial in a democracy where citizens are responsible for electing their leaders.

Unfortunately, millions of Americans who rely upon television as their primary source of news were misinformed; TV news coverage of the primary season, particularly cable TV news, failed the American public.

It’s true that earning a profit is important to sustaining any business. The days of news as a prestige loss-leader for the TV networks are long gone. But, the news business must measure itself by factors other than ratings and revenues because of its responsibility to the public.

So, it’s high time for TV news organizations to take a look in the mirror, commit to a serious review of their coverage of the presidential race and determine how they can better serve the viewers who depend upon them for accurate information.
