For reference, my question comes after having viewed the latest episode of the HBO series Silicon Valley (Season 3, Episode 9 - "Daily Active Users"). The final camera shot was a single, stationary camera overlooking a room crowded with people and computers. There was no dialog, narration, or music. The only audio on the scene was the ambient noise of the room (computer keyboards and mouse clicks, a few people quietly coughing or clearing throats, a squeaky door someplace off camera, etc). The shot lasts for 30 seconds (maybe longer, even a couple of minutes) as the credits begin to display, and all the way through to the last credit. The camera never moves, tilts, pans, or zooms throughout the shot.
I have seen this technique before, also on other Mike Judge productions (namely various episodes of King of the Hill). My question - Is there name for this particular technique or a history behind it? Someone who is noted for having used it or developed it as a signature technique? If Mike Judge is paying homage to others he finds influential, I'd like to be able to explore that history on my own, but I need to know where to start.
