90s-A and 90s-B. 90s-A was the first 5 years of the 90's decade and 90s-B is the last five years.
90's-A was all about VHS casset tapes being used to store video. I liked VHS, the tapes were the size of a small book and nested in a plastic sheath that opened on one side. For some reason the recording ones were usually sold in a pack of 3 for £5, something like that . You would push the tapes into a letter box slot on the VCR and a robot thing would snatch it from you, open the sheaf then press the tape onto a reading head, it was a missed opportunity in my view, they could have given the machine a barking sound like a dog when it ingests the cassette. 90s-A was about Games consoles that ran on a 16 bit processor so you could play side scrolling 2D games with a smooth finish and plenty of multilayered graphics. It is the birthplace of domestic internet, some clever guys realised that you could use a modem through the telephone to connect computers together with the existing commercial internet.
90's-B was all about games consoles that were powered by 32bit processors so the rapid memory was big enough to store many polygons and graphics, 3D open world games were being developed. It was about the Euro tunnel opening so you could take a train from London to Paris under the sea. It was about everyone realising what the internet was and trying to get it in their homes. Those days ISPs were just phone numbers that your modem would dial up but broadband was very close by. It was also about wide spread use of the DVD, I didn't like DVDs. I thought that the players that could record to them were very expensive and very unreliable.
