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.
