The Personal Computer Revolution: Crash Course Computer Science #25


Today we’re going to talk about the birth of personal computing. Up until the early 1970s components were just too expensive, or underpowered, for making a useful computer for an individual, but this would begin to change with the introduction of the Altair 8800 in 1975. In the years that follow, we’ll see the founding of Microsoft and Apple and the creation of the 1977 Trinity: The Apple II, Tandy TRS-80, and Commodore PET 2001. These new consumer oriented computers would become a huge hit, but arguably the biggest success of the era came with the release of the IBM PC in 1981. IBM completely changed the industry as its “IBM compatible” open architecture consolidated most of the industry except for, notably, Apple. Apple chose a closed architecture forming the basis of the Mac Vs PC debate that rages today. But in 1984, when Apple was losing marketshare fast it looked for a way to offer a new user experience like none other – which we’ll discuss next week.

    6:20 Lies! IBM wasn't "ignoring" microcomputer market. They introduced IBM 5100 at 1975 and so on till IBM 5150 at 1981 which we know as IBM PC.

  2. VOLKNER 117 says

    4:08 Steve Jobs? I believe you meant Michael Kelso.

  15. Isabela De Paula says

    Who else is here by of school

  16. Damian Woods says

    Love your videos; A few things 1. 7:00 I don't think CP/M was ever preferred or used by IBM prior to being offered in the 1980s as an alternative to MS-DOS. Earlier IBM PCs from mid 1970s (51xx just supported APL and basic). 2. 5:00 TRS-80 shown is not the 1977 model I as part of the "Trinity". This is the model III which came out in July, 1980.

  17. Elijah Ganske says

    Where is my guy John Green at

  31. Sam Stuart says

    The woman doing these videos is beautiful. Not supermodel beautiful, but the fact she knows about computers makes her pretty hot.

  37. gamefreak says

    USB, Im your father! Noooooo

  38. Damian G says

    really like the shirt

  39. Ramon Sanchez says

    Carrie Anne, you're brilliant and great fun to listen to, but you left out the Amiga Computer. After the Commodore 64, the Amiga became popular as a personal computer on par with the Mac, the Atari ST, and the IBM PC. It has a place in personal computer history as the first to offer a color interface and improved audio compared to other systems. It was the Amiga that inspired Apple and IBM to improve their graphics and audio.

  40. Chris Elmer says

    Why would early computer enthusiasts even want these? Sure £2k today is a lot of money for a beefy gaming rig and media editing machine, but I can't see how many people outside business would spend the equivalent momey on a oversized card puncturer. I'm surprised consumer available computers even took off so early as they did.

  41. Kushal Patel says

    I love that shirt.

  42. Floydsghost says

    Finally i get to see what was on that shirt!
