Have you ever messed around the Wayback Machine? This tool provided at archive.org or Internet Archive, lets you enter any URL and see what it has looked like over time. At least that’s what it is supposed to do.
The earliest incarnation of the Internet Archive, as displayed by the Internet Archive says:

Most people have accepted that some bloggers have important things to say.  And in the event people want to read those things more than once, Google Web History is now capable of tracking what they do through Google Blog Search.

A new feature from Google goes beyond the search history it can retain for people; their Web History option would keep track of every page a person visits.
