Honest question: why don't you include books as a media?
In comparison watching videos, playing tablet games, etc. comes nowhere close.
The differences are (1) the language in books read aloud is more often tailored to the child’s comprehension level, because parents can figure out whether books are too easy or too hard; (2) the range of grammar, vocabulary, styles, ideas, etc. is much wider in books than most kids get from other kinds of media; (3) the book is not a fixed medium but also has a live interpreter who can define or skip difficult words, repeat sentences rephrased a different way, answer questions, ask questions, go back to cross-reference earlier parts of the book, point specific things out in the illustrations, etc.
Anecdotally, the preschool kids around me whose parents read to them for 1+ hours/day seem to end up advancing about twice as fast in their language skills as their peers. YMMV.
The thing is: it’s hard to find actors for a play in the child’s bedroom at night. It’s hard for parent to come up with 200 different well-plotted stories at the appropriate level with visual props. Etc. But after 2 years of daily practice I can read a picture book decently (including funny voices, etc.) while half-asleep and consciously thinking about something unrelated with half my attention.
The kind of logical reasoning, grammatical variety, vocabulary, etc. used in books is not literally impossible to imitate with some other medium. It’s just a lot more work and in practice not really done.
Because, I don't know if you have children, I do (8 and 6): you can't read them a different book every evening for 1h. Even for more than 5 minutes.
You just can't. Life is messy, there's no place for such idealistic hobbies.
That's why I can't relate to those "advice" (too use kind words), I just don't think they are relayed by real parents.
