2. Before you move to next
• I listed the changes happened in Internet from 1992 to today (2010)
• This is totally my own view, so it could be wrong.
• I tried to be neutral, but I admit I maybe somewhat biased
due to my national background (Korea)
• Images are taken from Internet without getting proper permission,
some images may not be right for the content (don’t argue with this)
• Still in progress, so pages may be updated without prior notice
※ Regarding the images included in the slides,
I am not going to get any profit from this images. It is only to share.
If there is anyone who offended by my use of them, please tell me.
I will get rid of the image.
