This thinking about innovation is very common nowadays, but McLuhan wrote the following in 1964 and just has a particular way with words that I very much appreciate. From page 336 (of the ISBN 978-1584230731 edition):
Any innovation threatens the equilibrium of existing organization. In big industry new ideas are invited to rear their heads so that they can be clobbered at once. The idea department of a big firm is a sort of lab for isolating dangerous viruses. When one is found, it is assigned to a group for neutralizing and immunizing treatment. It is comical, therefore, when anybody applies to a big corporation with a new idea that would result in a great “increase of production and sales.” Such an increase would be a disaster for the existing management. They would have to make way for new management. Therefore, no new idea ever starts from within a big operation. It must assail the organization from outside, through some small but competing organization.
