We have come to rely on the internet in our daily lives and many of us would now struggle to live without it. In fact I would find it a challenge to teach without internet access these days as I have come to rely on the power of the information I can harness from it. But how did this powerful tool develop and how did it become to be classified as a human right to have access to it? Watch the youtube clip below and answer the following questions.

  1. Watch the clip below and write notes on the history of the internet. Below is a list of dates to look out for:
      • 1960 - Marshall McLuhan (Canadian) stated the world would become a 'Global Village'.
      • 1970 - US Defence - ARPANET
      • 1989 - World Wide Web created by Tim Berners-Lee (British)
      • 1993 - 60 countries accessed the internet
      • 1998 - 147,800,800 users, 52% of those were in the USA
      • 2001 - 326 million users, 67% English speakers
      • 2003 - Skype developed by Zennstrom (Swedish) and Frils (Denmark)
      • 2004 - 801 million users, 35% English speakers
      • 2004 - Facebook developed by Zuckerberg
      • 2009 - 1.464 billion users, 17% China, 15% USA

Activity Two - Skill

As you are all aware now being able to describe a graph is a fundamental geographical skill. When you describe remember to describe the overall trend illustrating it with figures, then describe the anomalies. Always back up your descriptions with data.

  • Using the graph below, describe the change in internet users within the UK.
