Technological change, as we know, tends to provoke linguistic and cultural change, too.
It’s the reason why, several times a year, dictionaries add in new and trendy words.

But more interesting than the new words are the old words that have gotten new meanings, such as cloud, tablet and catfish, which have very long pre-Internet histories.
So here, we look at words that had totally different meanings than they did when we were all kids.
