Children's Learning Network
Intellivision was promised as an educational as well as an entertainment product, and one of the first four titles released, reflected this. However, Mattel quickly saw where the money was -- sports and arcade titles -- and educational games were put on the back burner.
Only two titles came out as part of the orange-boxed Children's Learning Network. No others were even in development. (Partly this was due to the belief that the was better suited to educational games.) Each of these games ultimately sold just under 150,000 copies -- low by Intellivision standards.
