Twitter Celebrates 9th Birthday With Video of Kids Telling it How to Party

The microblogging service known as Twitter, which grew from Internet curiosity into essential media tool and social media channel, just turned 9 years old. To celebrate its milestone, the company, which launched in 2006, created a charming video that features 9-year-old children describing what that age means to them. Companies turning one year older aren't usually noteworthy until you start talking decades, but in this case, the video's cuteness factor makes it hard to resist.
