2 Interesting Technologies (Obsolete and not)

IRC (Internet Relay Chat)

IRC was created by Jarkko Oikarinen in August of 1988 it was a boom in Internet.

The first form of communication in real time that became popular on the Internet, the famous chat. The best way to meet people with your interests or in your area without getting up from your chair. There was no portal that did not have its chat, and IRC servers sprung up everywhere. 

Unfortunately among modern social networks and instant messaging programs they ended up killing him, but surely you still have good friends from a channel. 

Webcam!

The first webcam was released in 1991 by some lazy students from Cambridge university that wanted to check the coffee levels before going to buy them by then it was a huge progess. 

It is interesting how this was done and why and now how we are using them almost every week due to work stuff.
