When I first saw a video stream over the Internet in 1997, it was as sensational as it was bad. The RealVideo codec was quite groundbreaking at the time, but connected via a 56k modem the video was the size of a postage stamp (the things one put on postcards in the past), and the blocks were so coarse, that you often had the impression of sitting in front of Chaos-Tetris.

56k transmission speed was state-of-the-art at that time, in Europe you could only get faster with ISDN or a 1MBit sync leased line from Telekom (the latter cost about 5000€ per month in Germany as far as I remember).

Anyway, DialUp technology is interesting. Therefore RetroBytes has decided to take a closer look at the topic, and in his current video he leads us through the technology itself, over terminals to the construction of your own ISP.

Informative and entertaining. Definitely worth checking it out.
