The history of telecommunications is dominated by four different kinds of people who pushed forward technological progress, and changed the shape of the industry.
Some, like Graham Bell, were pure inventors only interested in technology for its own sake. The inventors set new benchmarks for what technology could deliver.
Others were primarily development engineers who took those possibilities and turned them into realities, using sound engineering and development skills. In doing so, they also created potential businesses.
That brought in the entrepreneurs. They weren't that interested in the technology but knew a business opportunity when they saw one.
Finally, there were the politicians, driven by ideology and conviction to bring about changes in the national or public interest.
