In the 90s it was rare to see a woman wearing a thong on the beach. Today more than 75% of women wear thongs. What year did the shift occur and who started the trend?
Excellent theory. It was caused by the advent of web 2.0, social media and Facebook in the early 2000s. Although one might attribute quite a lot of societal trends to the rise or social media.

Too young to remember a shift, sorry. I grew up seeing it, so "post-shift"
