According to an article in Online Media Daily, the latest installment of an ongoing tracking study from Interpublic’s Universal McCann unit reveals that text messaging, blogging and social networking have reached critical mass, with more than half of all adults in the U.S. using one of these to communicate with friends, family, or colleagues on a regular basis. But the big story — and it is huge — is that nearly nine of ten in the age group 18-34 use these, making it the most dominant form of communications for the group.

Yet we wonder why traditional media methods of communicating are dying.

In ten years, this group will be 28-44, and the new 18-34 year old group will be even more socially connected.

Text messaging, meanwhile, proves that mobile media also is becoming a dominant source of personal communications beyond the cell phone, even if mass marketers haven’t yet figured out how to crack the potential of marketing through the medium. The percentage of U.S. adults who say they’ve never sent a text message fell to 41% this year from 49% a year ago. And among 18- to 34-year-olds, it dropped to 22% from 38%.

The revenue opportunities of these applications haven’t materialized yet, but that should not dissuade us from participating. The most basic Web 2.0 tool is RSS, and I’m still amazed at how few media companies really exploit this as a content distribution method AND a revenue stream. The newspaper industry has had the Sunday inserts for decades, and one day, somebody will create a digital version that is distributed by RSS. Where will people access such feeds? There’s no reason it couldn’t be from local media companies.
