The correct option is C By playing to the audience, media giants that have engulfed journalism today have shattered the myth of detachment and compromised editorial sensibility.
The paragraph given argues that though journalism may have never been as public-spirited as it believed itself to be, the myth of detachment mattered, as it encouraged journalistic ideals such as standing up to power and not bending to the whims of the audience. In contrast, the guiding ethos of media giants that dominate journalism today is not detachment or editorial sensibility, but the relentless pursuit of the audience.
Option (C) sums up the main idea of the paragraph the best.
Option (A) talks of ‘editorial insight’ being engineered with the help of audience feedback loops. The paragraph, on the other hand talks of editorial sensibility/discernment, and expresses concern that media giants, in their single-minded focus on audience, have dashed the “crucial” myth of detachment that shaped journalism earlier. Option A does not touch upon this.
Option (B) is close, but incorrect, as it refers to “social-consciousness” that journalism exhibited earlier. The paragraph categorically states that journalism was never as public-spirited as it imagined itself to be.
Option (D) talks of a drop in the quality of journalism. The paragraph actually states the contrary. It only holds that editorial sensibility has been compromised.
