In a story on NPR yesterday(http://www.npr.org/templates/story/story.php?storyId=121146834), the correspondent said the five-game undefeated streak on Jeopardy 22 years ago by Ohio Attorney General Richard Cordray won him "notoriety". When I learned the word, "notoriety" was a negative type of fame or atttention. The use of the word in the NPR story, though, is synonymous with "popularity" or "celebrity". The NPR story is just the latest example of the transformation of the meaning of this word into it's polar opposite has become commonplace. I wonder how this happened. Are there other words that have undergone a similar transformation?
