Radio, TV, books, and newspapers have been part of mass media for a long time, it’s one of the biggest mediums of mass communications. It was originally meant to provide information for everyone, before mass communication, everything was done by word of mouth, It might not be necessary, it may die out, but it’s not anytime soon. Similar to how sites like Youtube might overtake television at some point in the future due to availability, easier to get wifi connection than satellite tv, mass communications might follow a similar direction. I do think that the mass communications we are familiar with will die out, it’s just not now, and if it changes, it’ll just take a different form. Such as books being converted to e-books, newspapers going online and splitting into individual articles spread by topic, and radios being converted to podcasts. TV will not die out, and at most will leave the satellite part of TV obsolete with everything converted to online streaming.
