The document discusses lessons that can be learned from the development of radio, television, and the internet and applied to the digital signage industry. It notes that these industries all followed a similar pattern: 1) domination by technologists and entrepreneurs in the early fragmented market, 2) adoption of business models and standards, 3) formation of networks that lowered costs and increased reach. It recommends that the digital signage industry focus on agreeing on standards like a common name, technical interoperability between platforms, and growing networks to accelerate adoption as these technologies took decades to reach critical mass and widespread use.
