Innovations are Often a Product of Collaboration and Iteration

Innovations like postboxes may not always be the result of a single individual's effort as seen in the case of the individual credited with introducing postboxes in the UK. While this person recommended postboxes to the government, the concept already existed in other countries like France and Belgium. The stamp was also invented before his recommendation. The introduction of postboxes in the UK could have been a collaborative effort over time even if he wasn't involved. This highlights that innovations are often a product of collaboration and iterative improvements rather than the work of a single individual.
