The way famous cities around the world look today is not how they looked several decades ago. Over the decades, things have changed a whole lot in the world. Technology has advanced, buildings have been built and cities have expanded greatly.

What this means is that many major cities look insanely different now than they did in, say, the 1950s. In just 70 years, cities have become a whole new world, and it is pretty interesting to see. Everything has changed in such a short amount of time, and everyone is around to experience it.
