As the article suggests, cord cutting isn't the sole issue. Cable networks seem to be clueless that they've abandoned their niches in favor of saturated content: reality shows and sitcom reruns. MTV & VH 1 don't play music videos anymore, TLC lacks educational content in favor of Honey Boo-Boo, and umpteen channels show Friends. Not to mention the original content channels produce seems watered down compared to their old offerings: examples BET, Disney Channel, Nickelodeon, and Cartoon network. Audiences aren't that dumb. Add to that, the heavy handed political messaging in shows. Viewers can tell when something is poorly written or cookie cutter and will turn away.
Broadcast tv is stale, it's current lineup of shows lack imagination compared to scripted streaming offerings.
Finally, we all know the problem with cable news. Sensationalism, hyper partisanship and toxic journalism that seeks to get eyeballs and reactions from viewers, rather than educating and informing them. With these poor choices, it's no wonder audiences are turning away from television.
