Page "Intellivision" Paragraph 16

In mid-1981, Mattel's upper management was becoming concerned that the Keyboard Component division would never be able to produce a sellable product.

As a result, Mattel Electronics set up a competing internal engineering team whose stated mission was to produce an inexpensive add-on called the BASIC Development System, or BDS, to be sold as an educational device to introduce kids to the concepts of computer programming.
