The film Man & Com­puter, made in 1965 by IBM’s UK branch, provides a basic under­stand­ing of com­puter oper­a­tions. A large por­tion of the film shows the ways in which a com­puter can be sim­u­lated by five people using the stand­ard office equip­ment of the day.

Start­ing in the 1940s, IBM became a major pro­du­cer of films used for sales, train­ing, doc­u­ment­ing busi­ness pro­cesses, enter­tain­ing at com­pany func­tions, and edu­cat­ing the pub­lic. Sev­eral IBM films were made by respec­ted film­makers and some­times fea­tured well-known actors.
