The phrase references the location of the original “turn on” function on YouTube’s platform, a rudimentary precursor to modern engagement features. Initially, this likely pertained to a simple system for activating video playback. While not a specifically labelled button, it alludes to the fundamental action of initiating video streaming on the platform’s early interface.
Understanding the historical context of this rudimentary function highlights the evolution of user interaction within digital media. The ability to simply initiate playback represented a significant initial step. Comparing it to contemporary features showcases how user engagement and video controls have expanded dramatically, adding layers of complexity and user customisation.
