The change that legacy media cannot overcome is they were a one-to-many model that was top down. Social media is many-to-many; a true marketplace of ideas.
Cable news relies heavily on discussions, opinions and speculation to fill up their 24-hour output. As the saying goes, "Facts kill discussions" so cable news has moved steadily toward "hot takes". Legacy media therefore has all the worst parts of social media but few of the good parts.
Social media is highly interactive, another aspect which legacy media declines to embrace. Many legacy media outlets which publish videos to YouTube have their comments turned off. Again, this is a holdover of the one-to-many model.
More than half of YouTube's content is watched on TV screens; not phones or tablets. So YouTube is steadily pushing legacy media out of the only place they had advantage.
Social media delivers a far bigger variety in far more formats than legacy media. 15-second clips is one format but 2+ hour podcasts as a completely different one, one that needs no screen and therefore makes it preferred for work and long drives.
Legacy media went from ignoring social media (~2004) to picking up key social media news stories that could not be ignored (2016 - Standing Rock) then back to ignoring social media content while demonizing the formats. I'm currently following the new version of Michael Moore, a humorous confrontational journalist who produces long form content. His story on, of all things, the theft of $200K worth of collectible Star Wars Lego sets by a Utah based chain, exploded over the weekend. 3 million views in 3 days plus many other content makers repacking his content. Part of my interest is to see if and when legacy media picks up the story.
Yes news is reshaped. Thanks for sharing that article.
