Where Are All the Teens?

Over the course of this year, I kept hearing reports about social media getting older. The largest age group of Facebook users is between 35 and 54, and this once college-oriented social network is now expanding the fastest among people 55+ years old.  Words also got out that teens are not that interested in Twitter either.  Apparently, while social media and social networking are all the rage in the business world, teenagers are not necessarily buying into the same excitement as we adults are.  These reports got me wonder: where are all the teenagers hiding?  I did some research, and these are a few popular teen hideout places that I have found.

1. Video Games

Pew Internet and American Life reports 97% of teens play video or computer games, and half of these teens play daily and typically for at least an hour each day.  In a separate report released by Nielsen, video gaming is also found to be one of the major media activities that teens engage in, and teenagers spend an average of 25 minutes each day on console gaming.  While some may see video gaming as an isolate activity, the Pew report suggests otherwise.  It shows that teenagers often engage in video gaming as a social activity, with 65% playing games with others in person and 27% with others over the Internet.  The most popular games?  Guitar Hero, Halo 3, and Madden NFL.

2. Mobile Devices

Mobile devices as a popular teen hideout came as no surprise to me as it has always been a challenge getting my undergraduate students not text message in the classroom.  Nielsen reports an average of 96 text messages sent or received by a teen in merely one day. But the story does not end with text messaging.  Nielsen also finds a higher than average consumption of mobile video by teenagers. The popular genres? Music, comedy, and user-generated videos.  Perhaps as even better news for businesses, an article from ClickZ offers evidence that teens are more receptive to mobile advertising than their adult counterparts.

3. TV and movies

TV is by no means a new medium, but it remains surprisingly popular among teenagers.  The same Nielsen report mentioned earlier tallies the time teens spend watching TV on an average day to be more than 3 hours. In a more in-depth rather than representative look at teenager media consumption, the 15-year-old intern Matthew Robson from Morgan Stanley says that teenagers’ TV watching is often driven by seasonality and scheduling of shows. When popular shows are on, there could be a big spike in TV consumption.  Popular shows among teens?  Nielsen lists Family Guy, American Dad, and American Idol.  Related to TV watching, teens also frequent movie theaters, seeing an average of 10.8 movies per year.  But despite high levels of interest in TV and movies, teens actually trail behind those 18-to-44 year-olds in online video consumption, watching just over 3 hours of online video in a month.  This does not mean teens are completely uninterested in online video, however, as both the number of teens watching online video and the time spent on online video are still increasing pretty fast. Only time will tell where the consumption level will settle eventually.

Does this picture of teenagers surprise you?  Do you have any additional information about teen media consumption?  Your comments are most definitely welcome.

Are You Targeting the Right People to Grow Your Community?

Last time I discussed a few research findings on what makes people pass on information to others.  This week, I would like to follow up on the topic and talk about a recent project done by Zsolt Katona (@UC Berkley) and his colleagues.  The research question Katona and colleagues set out to answer is what drives the growth of an online community. They surmised that the specific social network structure of the initial adopters affect the adoption likelihood of subsequent followers. To test their thinking, the researchers analyzed the first 3.5 years of data from a central-European social networking website, when no marketing activities had been engaged to promote the site and the network had been growing organically through word-of-mouth.  Here is the gist of what they found.

People do tend to follow the crowd but a more closely-knit crowd carries much more power

We all have hesitations when it comes to novel new things and may consider them risky. Depending on how risk averse we are, we may wait until some or a majority of other people have adopted the new thing before we jump onto the wagon. In my own research project documented in the last blog, we found the median adoption threshold to be 50%, incidentally supporting the “majority rules” mentality. But the threshold reported by our sample ranged across the whole spectrum from 0% to 100%. Consistent with this idea of an adoption threshold, Katona and colleagues found that more people in one’s social circle adopting a social network makes one more likely to join the network. In this context, perhaps an additional driver besides risk is the fact that the utility of a network increases when more of one’s friends belong to it. The story does not stop here, however. The researchers also found that a closely-knit (or high-density in network science terminology) network where everyone knows everyone else is much more influential. If the same number of individuals in a closely-knit network joins a social network, the remaining non-adopters are much more likely to follow suit than if it were a loose (low density) network of sorts.

Network

Social butterflies are not the most influential

In network science, the fact that some individuals have way more friends/connections than most others in the same network has often been compared to the rich get richer phenomenon.  But unlike the richer people who do have solid cash to spend, social butterflies who have tons of friends (think 1000+ or even 500+ Facebook friends) are actually quite weak when it comes to influencing other people’s opinions. Well, at least when it comes to the decision to join a social network any way. This may be surprising on first look. But not so when one thinks deeper about human psychology. We all have limited energy to build and maintain friendships. The more friends we accumulate on a regular basis, the less energy we have to develop a deep and meaningful relationship with each individual, and thus the less we are able to exert a strong influence.

Weak ties may be good for information travel but exert limited influence

The strength of the weak tie has been a well-known phenomenon for more than 20 years, referring to the fact that weak ties that link disconnected networks are critical to the spreading of information. However, for exactly the same reason, the central role played by these weak ties also makes a network formed around such ties more vulnerable.  Referring to these individuals as structural holes, Katona and colleagues found that the adoption of a social network by these structural holes has less of an impact on their friends, perhaps accurately reflecting the fact that these are “weak” ties.

Lessons learned

  • Many factors create counter effects when it comes to increasing awareness of a community vs. increasing participation in a community.
  • While sometimes it may be necessary to target loosely-knit networks (more weak ties) for increasing the awareness of your online community, closely knit networks are eventually critical to increasing actual participation in your community.
  • The same thing goes with highly-connected individuals. While those who have lots of friends may be good for getting the word out, individuals who have a more moderate friend circle may be more ideal for building the community.
  • For a business, how these counter effects should balance out will depend on the exact goal for the online community at each stage.
