“Personalization” versus “Individualization” [...]

What is the history of the term "personalization" particularly as it relates to education (and education technology)?

See Google's Ngram Viewer:

The OED dates the word "personalization" in print to the 1860s, but the particular definition that's used today -- "The action of making something personal, or focused on or concerned with a certain individual or individuals; emphasis on or attention to individual persons or personal details" -- dates to 1903. "Individualization," according to the OED, is much older; its first appearance in print was in 1746.

Something happened in the 1960s, according to the Ngram data at least. We see a peak of "individualization." "Personalization" took off dramatically a few decades later, circa 1995 and 1996. Was this related to the Web?
