What are some incredible photos showing how much the world has changed in 100 years?

But producing "incredible photos" is difficult because we wouldn't have many photos of 100 years back, would we?

The first digital photo was taken only in 1957 after all.

So, the following photos don't really have a difference of "100 years". Take it as just old and new, which is sufficient to underline the progress we have made and how far we have come.

These are some of the many differences you'll encounter when comparing today with the old days. FROM the house we live in and the lifestyle we have TO the infrastructure around us and the overall culture -- everything has changed.

But then you don’t need pictures to understand them. Just ask your dad ;)
