[Star Wars] What's the deal with the droid army manufacturers?

 I originally thought that the Trade Federation had providing the CIS with their droid army. But from _Attack of the Clones_, it seems that the Techno Union originally provided them with droids, but then the Trade Federation later joined and chipped in.

  Though from what I've read, a certain company, which is Trade Federation property, created the B-1 droids. But it seemed that the owner of the Techno Union managed that company. And the B-2 droids were created by the Techno Union.

  Did both corporations create B-1 droids? Which corporation supplied first? Which types of droids were made by which corporation? What is the relationship between these corporations?

Both groups worked together to get the Droid production up and running. Techno Union provided the scientific and engineering know how to make the Droid and the TF funded the building of factories and aquire resources.
