This is TALK OF THE NATION. I'm Ari Shapiro, in Washington. Just one week into January, you may be noticing the effects of people's New Year's resolutions. For example, there may be no spots on the treadmill at your gym; no kale on the supermarket shelves. Losing weight is one of the most popular New Year's resolutions and this hour, we'll explore what we've learned in the last year about how some people keep fit, and why others have a hard time dropping pounds.
Now, this week, the American Dialect Society announced its word of 2012, and the winner comes from Twitter. The word is hashtag. The symbol for a hashtag looks like the pound sign on your phone. Five years ago, Twitter introduced it as a way to organize tweets and sort through trends. Now, hashtags are everywhere. Movie trailers use them to promote the latest blockbuster, shirts and hats sport the hashtag #YOLO for you only live once. Hashtags even pop up in conversations with friends like hashtag #eyeroll.
Southern Louisiana in the early 1960s was a hotbed of musical creativity among youngsters who'd been raised listening to French-language country music and Fats Domino. They combined those — and other — influences to make what's now called "swamp pop." Joe Barry was a pioneer in this area who should have been much bigger.
