I am so glad someone said this! I get really mad when a PR person writes the word content in the press release for my company. We don't create content.
To me "content" means you don't know what you are making or you are very embarrassed about it. We make art or entertainment that people pay for.
In general there are two axis I think about in media. One axis is originality, the other axis is durability. Very unoriginal is a transcription of information everyone already knows. Investigative reporting that reveals new information is very original. A creative story is original.
Durability is how long the thing will have some value. They can put the Wizard of Oz in Sphere today. A Tik Tok video will probably be forgotten in a day or two. You could call that "quality" but that's harder to define and measure.
Value is created in being as original and durable as possible. Platforms want you to be the opposite-- that's the slop they call content.
