Story highlights

CNN Special Report #Being13 analyzed 150,000 social media posts of 13-year-olds

Acronyms or slang teens used ranged from innocent to racy

CNN  — 

For the sake of this story, I’d like to invent a new acronym: IAVS, which means, “I am very sorry.”

The reason for the apology stems from a story I wrote last year, “28 Internet acronyms every parent should know.”

“Wouldn’t it be interesting to do a piece on the acronyms that teens are using across the Internet, especially on social media and apps, to help parents understand what, in fact, their kids are talking about?” I thought.

I consulted existing lists of Internet acronyms and talked with Internet safety experts. It seemed fine – until the story published and I received a wildly critical response on social media, often with language that I can’t include here.

My Twitter feed blew up with people saying I didn’t know what I was talking about and that teens weren’t using most of the acronyms on my list.

Here’s why I’m sorry: For that story, I never consulted with the true experts – teens, themselves.

I’m thankful to have a chance for a re-do, and this time I know we’ll get it right because our list comes straight from the social media posts of 13-year-olds around the country.

As part of a two-year investigation, #Being13: Inside the Secret World of Teens, Anderson Cooper and his “AC360°” team connected with 200 eighth-graders at eight different schools around the United States. They, along with their parents and schools, gave CNN and two child-development experts permission to review what they were posting on Instagram, Twitter and Facebook over a six-month period.

The end result: 150,000 posts written by 13-year-olds. They speak volumes about how teens communicate and what impact social media has on their lives. (The CNN Special Report “#Being13: Inside the Secret World of Teens” airs at 9 p.m. ET Monday. Watch to find out the results of the first large-scale study of its kind on teens and social media.)
