One of the best things that Google has offered me/us is the Google News Archive Search. Users can type in any word or phrase and Google will search as far back as the news goes and report news stories that contain your search word.
A search for “sweatshop” shows that the use of the term has been falling from 2000 to present.
“Fair Trade labeling” has a spotty presence in the news.
What is most encouraging perhaps is the use of the word “sustainability.” Usage goes from near zero levels in the 1990s to off-the-charts.
Just a little exercise in data analysis.
