For a glimpse at the country’s divided political reality, look no farther than a pair of television studios on opposite sides of the Avenue of the Americas in Midtown Manhattan.

From her set inside MSNBC headquarters, Rachel Maddow opened her prime-time coverage of the Trump impeachment hearings by calling the first day’s testimony “a double-barreled problem for the president — triple-barreled, maybe.” President Trump, she said, had been “caught doing something illegal” at the “direct expense of the country’s national interest.”

One block south, from a Fox News studio, Sean Hannity welcomed viewers by declaring “a great day for the United States, for the country, for the president — and a lousy day for the corrupt, do-nothing-for-three-years, radical, extreme, socialist Democrats and their top allies known as the media mob.”

These distinct visions — delivered simultaneously from skyscrapers roughly 1,000 feet apart — were beamed at the 9 p.m. hour into millions of American living rooms. It was a striking reflection of today’s choose-your-own-news media environment, and a far cry from the era when Americans experienced major events through the same television hearth.
