virability
n.— «Fallon, for example, is launching a microsite today for its Garmin campaign. The site will have an extended 60-second version of the ad, a 2 ½-minute music video based on the ad, lyrics to the music video and the guitar notes to play it. There’s also a facility to encourage what’s called the “virability” of the ad—an icon to click on and send the ad to a friend.» —“The ad game continues to evolve” by Gregory A. Patterson Star Tribune (Minneapolis, Minnesota) Feb. 2, 2007. (source: Double-Tongued Dictionary)

Use of the word in our halls and meetings began slowly about 4 years ago. Now we have in house “Virability Gurus” who seem to have created a new specialty area.
