AOL was your ISP - you would connect via your telephone line instead of cable/fiber. Your modem would call their number and establish a connection. No one else could use the phone while you were online.<p>When you connected, it would load the AOL application which contained most of what AOL offered - built in AIM (AOL instant messaging), a web browser, group chats, keyword search, email, etc.<p>You were still connected to the internet and could use alternate browsers, but most people stayed inside the AOL app and ecosystem. Keywords were a time before search, where companies could buy keywords (from AOL) and then when people searched them they would show up. It was kinda a separate system from DNS that AOL tried to profit from.<p>You had competitors like Prodigy and CompuServe offering similar dial-up + custom app offers.<p>You wouldn't use the AOL app without having AOL dial-up service (although I recall them offering it separately late in its life, bring your own internet). People thought "AOL" was the internet. You might recall the classic "You've got mail" movie. That was from the AOL app which loaded after connecting.<p>aside: It's crazy how AOL could have become Facebook. AIM chat was the main focus - but AIM had "profiles" which you could customize, and I did - even with daily status updates. Modern Facebook is basically the reverse - profiles with a chat attached.
AOL started off as something different from an ISP.<p>Like Prodigy and Compuserve and GEnie and some others, it was an on-line information system. Chat, message boards, news, stock quotes, (limited) shopping, games, software downloads, etc. But all within a single system. Kind of like a nationwide/global BBS, but with a GUI interface. In the 80s, all these systems were independent, in the early 90s they got internet email, and the mid 90s added web browsers and (eventually) real tcp/ip.
I was pretty young at the time, but I think it started as basically a BBS. With an Internet backbone so a bunch of local numbers could all access the same server. They added Internet access later, and initially only via their own browser.
In the early 1990s, back before anyone was ever sure if this Internet thing would ever take off outside of academic communities (and also ostensibly before Sir Tim-Berners Lee invented the World Wide Web), America Online was a proprietary online community that was reached via dial-up modem over the telephone network.<p>AOL allowed their users to interact with eachother (chats, forums, multiplayer games), read news, and otherwise kill some time. It was a walled garden that required both money and special software to access.<p>There were other paid services that were vaguely similar, each with different shapes for how the walls of their respective gardens were arranged. In the US, some of these competing services were CompuServe, Prodigy, GEnie, and Delphi.<p>Of all of these, AOL became the most-broadly known. As time moved on, they increasingly would mail out floppy discs with their software to millions of households on what seemed like a continuous basis, with flashy color brochures, to millions of homes. (Some weeks I'd wind up with as many as 3 or 4 new AOL disks to use for whatever, delivered right to the mailbox on the front porch. Later, they'd send CD-ROMs instead that were most-useful as drink coasters.)<p>These services each vied to get as many users locked into their garden as possible, which was important to them because they tended to be metered services: Unlike something like a Netflix or Hulu streaming account, the more time a person spent using these services, the more money they had to spend.<p>And then, September came again -- and it never ended[1]. The walls of the gardens began to open up and users of these proprietary services began being exposed to what the greater Internet had to offer.<p>But at the same time, AOL grew. They got proper-fucking big. They went from being a cheeky dialup service with a friendly interface and some pervasive advertising campaigns to buying Time Warner for $182 billion.<p>And today, all of that business is just kind of a dusty memory.<p>[1]: <a href="https://en.wikipedia.org/wiki/Eternal_September" rel="nofollow">https://en.wikipedia.org/wiki/Eternal_September</a>
