In an article I read some years ago the author pointed out how the American church is typically 5 to 10 years behind world in adopting the worlds ways.
While he cited several things to make his point, the main and most clear point he focused upon was swimwear. Starting at the beginning of the 20th century he showed how each time a new, more revealing (and they weren't revealing much at that time) swimsuit came out the church would denounce it and preach against it. Yet in a few years when the next new and a little more revealing style came out the church would denounce that while adopting the previous one as suddenly acceptable.
The author followed that trend all the way up to today. He did similar with music, movies, games, premarital relations, divorce, etc.
