During this period, Pixar continued its successful relationship with Walt Disney Animation Studios, a studio whose corporate parent would ultimately become its most important partner. As 1991 began, however, the layoff of 30 employees in the company's computer hardware department—including the company's president, Chuck Kolstad, reduced the total number of employees to just 42, approximately its original number. Pixar made a historic $26 million deal with Disney to produce three computer-animated feature films, the first of which is "Toy Story", the product of the technological limitations that challenged CGI. By then the software programmers, who were doing RenderMan and IceMan, and Lasseter's animation department, which made television commercials (and four Luxo Jr. shorts for "Sesame Street" the same year), were all that remained of Pixar.
