|Colombian Press made circa 1860|
Charles Dicken's, The Pickwick Papers and Arthur Conan Doyle's, sequel to A Study in Scarlet were first published by magazines. I don't know as to how many of these magazines were published, but I do know that putting it into print was a labour intensive process.
Recently I came across an exhibit in, the National Museum of Scotland, that it seems revolutionized printing in the 19th century; the iron hand press replaced wooden presses and was invented by American, George Clymer in 1813. Unfortunately George's invention wasn't received as well in the US and he moved to the UK to put it into production and the one featured was made in Edinburgh.
If you think how far publication has come in two hundred years, I wonder what people will be saying about our digital world in two hundred years time.
