The Google Toolbar adware installer component itself (the "Google Updater" or something like that) that you remember in installers eventually silently upgraded to a Chrome installer. Almost every installer that ever installed Google Toolbar was automatically a Chrome auto-installer, "thanks" to software as a service. If you didn't uncheck hidden "Google Toolbar" checkboxes, that would also auto-install Chrome. (That added to how hard it felt to keep Chrome from ever being installed on a machine, because sometimes you'd overlook the "Google Toolbar" in older installers as yet another trojan horse for Chrome.) Eventually the Google Toolbar itself would just auto-upgrade to Chrome as well. Anecdotally, my father liked the Google toolbar for giving a separate search box in IE, but disliked Chrome and was confused when Chrome auto-installed and the Google Toolbar partly became a big ad for "congrats, you can use Chrome now", and that was one of his reasons to (finally) switch to Firefox for good (he used both IE and Firefox for a long time prior).
