The word "shareware" really comes from a pre-internet era, where distribution of software was a challenge.<p>So the idea is to let your users do the distribution for you, please, you are free to share this software with your friends by letting them have a copy. Or by putting it on a dialup BBS download area. Or by including it on a CD you try to sell people of thousands of mostly crappy shareware/freeware ('freeware' another word that's sort of been eclipsed by the 'open source' revolution), which people are still happy to pay $5 or $10 for, because it was hard to get software otherwise, people didn't have access to an internet with all the software!<p>Shareware often had all software features unlocked immediately, but encouraged people to pay if they liked it and continued using it. Or maybe not 'encouraged', often "required" by terms of the license, but with no real enforcement mechanism, really just the honor system<p>Or occasionally locked some features until you had bought a license -- but that was rare in the pre-internet era, because there wasn't a good cheap way to exchange money for license keys, that didn't require building up an expensive infrastructure.<p>All of these business models are still in use. For instance, you can download SublimeText for free, and use it as long as you want -- buying a SublimeText license does nothing but disable the popup message on startup that says "Please buy a license if you find this useful." I forget the language it uses, how strongly it tries to tell you that you _must_ buy a license to continue using it, but either way it'll let you keep using it forever with the startup popup message, without paying. It's essentially "shareware" as far as that goes -- but there's no need for users to obtain a copy by their friends who already have a copy 'sharing' one; everyone can just download a copy from the ST website themselves.<p>Some things that basically use this 'business model' are actually open source -- you legally _can_ use the software for whatever you want without paying for it, but if you'd like to support the developers, send money. That's sort of "shareware" too.<p>But now that it's pretty easy/cheap to set up your own website for people to download software, and sell license keys over the website, and have the software be feature or time-crippled without the license key -- people who really want to require the users to pay in order to keep using the software are more likely to do that. And we don't call it "shareware", it doesn't need a special name, because it's such a common way to do it now, maybe even the predominant way to do it.<p>The term 'shareware' is from a pre-internet era, and from an era before open source caught on too (and open source catching on came along with the internet era too). And there's no reason to buy a CD of a compilation of mostly crappy freeware/shareware anymore, everyone can just browse the internet and download whatever they like.
