Did you watch the livestream of the Atlantis Space shuttle launch last week? In case you missed the live version check it out on YouTube, http://www.youtube.com/watch?v=duH4rq7WJoU.

Presidential speeches, company press releases, police scanners, and sports can be streamed live across the web.

The Social Media suggest companies use livecasting to introduce or demonstrate a new product, share preventative maintenance program for consumers, or interview an expert about the new developments in the industry.

People have been broadcasting their lifes live since the 1980s. It all started with Steven Mann, whose work led to the Wearable Wireless Webcam.  In my eyes this was one of the earliest forms of reality TV shows. He was the first to livecast his life live 24 hours a day, 7 days a week in a continuous stream. During his livecast he encouraged his viewers to communicate with him through text messages.

Livecasting is another free opportunity for businesses to communicate their message to consumers. I have said it, and I will say it again – it’s all about building your companies Google Juice. When consumers search your companies name what content appears? It should be content generated and controlled by you so consumers are getting a cohesive brand message.

In 1994, the Rolling Stone became the first band to stream a concert live on the internet. The technology allows users to create virtual worlds and businesses with livecasting. Many companies hold annual meeting, seminars and e-learning via webcasts.

Justin Kan keyed the term livecasting in 2007 when he launched “Justin.tv”. Justin.tv began as a lifecast of Justin’s life 24/7, like others had done before him. A few months later the site Justine Ezarik became the second to livecast her life on Justin.tv. And yet another couple months later Justin opened the site to the public.

Livingcasting has since expanded. Not only do people broadcast their lives but also live discussions about numerous topics at many different times.

Charlie Sheen, after his media debacle early this year, started a live broadcast from him home on UStream.tv called Sheen’s-Korner. The description for the channel reads, “You’re either in Sheen’s-Korner or you’re with the trolls.”
