I'm giving a speech on usability, and want to make some points about how
long it took from Gutenberg invented the (first commercially successful
moveable type) printing press until various useable features were
introduced. I used to have references that covered this, but I can't
find it anywhere.
when was variable witdh spacing introduced (rather than cutting types
in varying widhts as Gutenberg did)?
when was paragrpah indent and newline introduced (rather than
separating paragraphs by paragraph marks)?
any other noticable inventions that should be mentioned?
