According to Merriam-Webster, the word McMansion first appeared in 1990. What words came with it? From the Time Traveler in 1990:
This is an interesting list of terms that have now existed for thirty years. Like the McMansion, these refer to newer phenomena that either did not exist prior to 1990 or did not have a reason to be named.
But, just because terms were introduced does not necessarily mean that they were used at the same rate over time. Using Google NGram Viewer, here are some of the terms in comparison:
Take out the tech terms – World Wide Web and spam – and now some of the patterns regarding other social phenomena are more clear:
Since this covers books, there might be a lag compared to other sources. For example, my own analysis of the use of the term McMansion in the New York Times and Dallas Morning News found the term had higher rates of usage from roughly 2005 to 2008 (and then plateaus, just as it does with book usages several years later). But, it also takes some time for terms to be used widely. Indeed, three of the five terms above steadily rise in usage.
Given the time travel back to 1990, it might be hard for any new words to compete with computer or Internet related terms. The introduction and spread of the Internet shaped many aspects of society. At the same time, new understandings of sexuality and relationships are pretty influential as well. Perhaps thirty years is not enough to judge the impact of these words just yet.
