Read too much film and TV industry technical literature, and it’s easy to get the impression that everything about the technology is built to carefully considered specifications. As Philo Farnsworth’s wife was probably aware, though, as he tinkered with the electronics while she sat in as a test subject, it’s often the other way around.
