New MSNBC promo: 'This is not an echo chamber'

MSNBC recently launched a new on-air promotion that claims the cable news network "is not an echo chamber."

"This is not an echo chamber," a narrator says to begin the 30-second MSNBC ad, titled, "This is a dialogue."

The ad features political sound bites from MSNBC hosts including Chris Hayes, Joe Scarborough and Rachel Maddow as the 1972 rock song "Join Together" by The Who plays in the background.

"This is not a one-way street. This is a dialogue that looks at the world and all its complexities from every side," the narrator continues.

"It’s exactly what the founders of this country imagined," Chris Matthews declares in a clip as the ad concludes with the MSNBC logo and the caption: "This is who we are."

The network has added some Republican commentators to its hosting roster in 2017, including former George W. Bush spokesperson Nicolle Wallace at 4:00 p.m. weekdays and Salem Radio's Hugh Hewitt at 8:00 a.m. on Saturdays.

MSNBC has surged in 2017 as an unpredictable Trump presidency provides a boon for the politics-heavy cable news industry.

”The reason this is so wild is no matter what you think of Donald TrumpDonald John TrumpTrump nominates Jeffrey Rosen to replace Rosenstein at DOJ McCabe says ‘it’s possible’ Trump is a Russian asset McCabe: Trump ‘undermining the role of law enforcement’ MORE, he is unconventional," MSNBC President Phil Griffin told The Hill in an interview earlier this year.

"Every day, by noon, we are on to a different focus and topic. And strange things happen and we have to be on it, and fact check it, and look at the historical perspective, and see how the country is taking it all in," Griffin, who renewed his contract with the network in May, added.

"The Rachel Maddow Show" has helped fuel the left-leaning network's success, finishing the third quarter, which ended in September, as the most-watched cable news show on television. The victory marks the first time an MSNBC program has finished first in the ratings, according to Nielsen Media Research.
