Possibly related to that period having two world wars and the Cold War? If I look a lot of the inventions in that timeline, they're related to or directly funded by warfare. Consider radio and radar, rocketry, space flight, the Internet and its related technologies, there's a very big list. In the US, institutions like DARPA were directly funded for that purpose.
