Why is the modern mass notification system considered a collaborative invention?

Answer

It involves combining existing telecommunications, broadcast, and software protocols.

Modern mass notification systems are not the product of a single inventor but the result of layering various communication methods and software advancements over time. These systems synthesize contributions from telecommunications engineers who built infrastructure, broadcasters who adapted signals, software developers who created dispatch algorithms, and cellular providers who facilitated message delivery, resulting in a complex, multi-modal protocol for crisis communication.
