copyright i said;
Copyright was invented after the advent of the printing press and with wider public literacy. As a legal concept, its origins in Britain were from a reaction to printers' monopolies at the beginning of the eighteenth century. Charles II of England was concerned by the unregulated copying of books and passed the Licensing Act of 1662 by Act of Parliament, which established a register of licensed books and required a copy to be deposited with the Stationers Company, essentially continuing the licensing of material that had long been in effect.
apparently patents are slightly earlier
Patents in the modern sense originated in 1474, when the Republic of Venice enacted a decree that new and inventive devices, once put into practice, had to be communicated to the Republic to obtain the right to prevent others from using them.
Why do I state my opinion if I don't think I can change US Law? I happen to not live in the US, so i pontificate from my soap box that lets me talk to Americans that could, possibly, affect the process, though i still maintain the US Congress is largely bought and paid for. Fortunately, in Canada, our campaign funding laws are much more focused on individuals, and thus our political process is much more heavily influenced by individuals; so here I actually have a chance. But American laws have a weird way of spilling over the boarder (if you'd respond about why should i care if i'm not in the US) to Canada.
Sure people *CAN* freely share information; but what if, like the music industry, they simply lock everything away in a vault unless you pay through the nose for information which is infinitely copyable and thus lose their value on a per-copy basis. Or academic papers/journals and the insane licensing fees to read them. &etc
I know what you mean about grass roots movements, but it's also made massive surveillance and enforcement of things much easier too. It will be interesting to see how things play out; I certainly hope your instincts are correct, but I tend to be somewhat cynical about those matters.
