Intermodal container
Modern form
Containers in their modern 21st-century form first began to gain widespread use around 1956. Businesses began to devise a structured process to use and to get optimal benefits from the role and use of shipping containers. Over time, the invention of the modern telecommunications of the late 20th century made it highly beneficial to have standardized shipping containers and made these shipping processes more standardized, modular, easier to schedule, and easier to manage.
Modern ISO standards
ISO standards for containers were published between 1968 and 1970 by the International Maritime Organization. These standards allow for more consistent loading, transporting, and unloading of goods in ports throughout the world, thus saving time and resources.
Impact in worldwide supply shortage of 2020 to present
Some experts have said that the centralized, continuous shipping process made possible by containers has created dangerous liabilities: one bottleneck, delay, or other breakdown at any point in the process can easily cause major delays everywhere up and down the supply chain.
