Clothes always had a social signalling component. The signalling dynamic shifted, becoming both increasingly accessible, capable of defining increasingly finer social groups,
esspecially those
not associated with high-powwer or high-status groups (nobility, royalty, clergy, miltitary, artisans, merchants).
Fads-as-signalling shows up in many places if you look for it: https://old.reddit.com/r/dredmorbius/comments/62uroa/clothin...
Information is ... somewhat trickier. Clothing is manifest and overt. Information ... mostly isn't. (Memes, logos, jingles, musical hooks, and slogans being prime exceptions.) Possession of specific information becomes a credible (expensive to obtain, hard to falsify) indicator of strong group identity --- whether you're talking about membership within a religious sect, programming subspecialty, profession, banking cabal, political party, or neihbourhood gang. Various fandoms seem to be a reasonably benign (for now) expression of this.

The total number of titles in Europe at the time was about one million. Today, one millon titles are published per year. (http://www.bowker.com/tools-resources/Bowker-Data.html) On average, that's one book per 330 Americans. Who read fewer than one book per year, on average.
What does it mean to publish if what's recorded is never read? The old WORN drive joke (write once, read never) has fangs.
Or if different cultures (religious, geographic, professional, political,...) share no common literary or informational references?
