That depends. Yes, the cable standard did carry broadcast TV with commercials, but a big selling point in the beginning was also the existence of cable only paid TV channels that did not have commercials. Premium cable as an offshoot of cable only networks also did not have commercials, it was a major selling point. As the medium expanded and the channel breakdown shifted commercials came back in a big way, and even many premium channels got commercials. Prime examples would be USA Networks, HBO, Nickelodeon, and quite a few more.
The scene was like an example reel from a video game, greenscale-ish translucent humanoid mannequin standing in a pseudo void, with a nondescript rectangular table of a similar greenscale-ish semi translucent material, and only the ball is “finished” as it is the camera focus. It is approximately between baseball and softball size, smooth, but I did not pay attention to the color. There is an “interaction/activation” sound effect as the mannequin kinda leans over and lightly pushed the ball to cause it to roll. It rolls to a stop on the table top, and this action loops.
The center of focus pulled back as I read the questions, more becoming aware of them than choosing them, and the scene changed with a camera pull out as part of the “ball is pushed” tutorial clip.
I have realized how much growing up as a gamer as influenced my perspective.
