At IFA, the annual gadget gala taking place this week in Berlin, the world's consumer electronics companies are showcasing their latest gizmos.
These historic photos provide a nostalgic reminder of how quickly tech becomes obsolete. Even the so-called booth babes have evolved.
IFA dates back to 1926, but this retrospective begins in the 1970s, when the show became an international affair, rather than a strictly German one. That was also around the time that colour TVs started to become more prevalent.
Here's a photo of ladies welcoming attendees to IFA in Berlin in 1973. Note the show logo, which is still used today. Wunderbar!
