I recall when I was first called an "Internet Personality." It was at a convention, and that was how I was described in the program booklet. That was quite a few years ago, and it seems that over time in the age of the internet, megamedia, and 24-hour news cycles the world is filled with "personalities."
Personalities are everywhere. News personalities. Internet personalities. Writers are personalities. Colorful local personalities. It seems some of the most successful (or at least famous) people we know are, well . . . personalities.
