Mason has become mega-popular, hitting the Number 2 spot in 2011, by far the highest its ever been on the Social Security list.

Mason is an occupational surname that's been heating up for several years, a fresher sounding replacement for the Jason we've moved way beyond, in step with the newer style Cason/Kason.

Mason has been getting a lot of reality-show media attention since it was chosen by Kourtney Kardashian for her son, but it's been used by several other celebs as well, including Cuba Gooding, Jr., Melissa Joan Hart and Kevin Richardson (as well as by Kelsey Grammer for his daughter).

Currently there are two cute TV werewolves named Mason: Mason Greyback on Wizards of Waverly Place and Mason Lockwood on Vampire Diaries--a far cry from the name's wholesome image.
