The containerisation revolution, despite being centered on a relatively simple technology, did not take over the cargo shipping industry until the 1960s. This paper argues that the timing of its introduction was determined by organisational as opposed to technological factors. This argument is developed by looking at the events leading up to the introduction of containers into cargo shipping. The rapid spread of containers and the role of standards are also considered. Nonetheless, given the nature of finding coherent organisational patterns and complementarities, it is argued that informational externalities were most probably responsible for any delay in the container system’s introduction.
