Internet Archive 
How long have you been on the internet? Probably not as long as Yahoo or even Microsoft has been. If you’d like to take a step back into the past, visit today’s cool site so you can see what a certain website looked like.. Say.. 5 years back. Just go to the “Wayback Machine” at the Internet Archive.
For example, take a look at Microsoft.com back in 1996 compared to what it is today. It’s amazing how websites transform from something simple to complex sites.
Even better, pull up a search for worldstart.com and see what we looked like back in 1998. Neato.
If you can’t find a certain website, then you can always add it to their database for future comparison.
