Did you know?

Friday, May 4th, 2012

You could fit the whole Internet on just 200 million Blu-Ray disks and the first webcam was used to monitor a coffee maker?

The technology behind the Internet began back in the 1960′s at MIT. The first message ever to be transmitted was LOG. Why? The user had attempted to type LOGIN, but the network crashed after the enormous load of data of the letter G. It was to be a while before Facebook would be developed…

The Internet began as a single page at the URL http://info.cern.ch/hypertext/WWW/TheProject.html, which contained information about this new-fangled “WorldWideWeb” project, and how you too could make a hypertext page full of wonderful hyperlinks. Sadly, the original page was never saved, but you can view it after 2 years of revisions here.

Other interesting internet trivia:

  • The first webcam was deployed at Cambridge University computer lab – its sole purpose to monitor a particular coffee maker and hence avoid wasted trips to an empty pot.
  • Although the MP3 standard was invented in 1991, it wouldn’t be until 1998 that the first music file-sharing service Napster, would go live, and change the way the Internet was used forever.
  • Ever since the birth of the Internet, file sharing was a problem for the authorities that managed it. In 1989, McGill University shut down their FTP indexing site after finding out that it was responsible for half of the Internet traffic from America into Canada. Fortunately, a number of similar file indexing sites had already been made.
  • Sound familiar? Even today file sharing dominates Internet traffic with torrent files accounting for over 50% of upstream bandwidth. However, a larger proportion of download bandwidth is taken up by streaming media services such as Netflix.
  • Google estimates that the Internet today contains about 5 million terabytes of data (1TB = 1,000GB), and claims it has only indexed a paltry 0.04% of it all! You could fit the whole Internet on just 200 million Blu-Ray disks.
  • Twenty hours of video from around the world are uploaded to YouTube every minute. The first ever YouTube video was uploaded on April 23rd 2005,by Jawed Karim (one of the founders of the site) and was 18 seconds long, entitled “Me at the zoo”. It was quite boring, as is 99% of the content on YouTube today.
