IBM PC Clones (1985)
I found this one very interesting. Back when the idea of the "PC" was still in flux.
I really like the commentary about avoiding the PC platform to encourage innovation. Today that would be systems like ARM based desktops or Sparc servers.
Funny that today IBM is the one company not in the PC market at all. The IBM platform is Power, PC mostly belongs to HP, Dell and Lenovo.
They also show the brand new Infomart in Dallas very close to my home there.
