I think it was a Nike ad, from some time ago. There was a black background, and a white diagonal line across the screen. As this music played, the line represented different things. It was a goal line, a lane line for a runner, a chin up bar, etc, all transitioning smoothly to music. The line and background never changed – the athletes just popped into view over the background, and the line represented a line in their sport. Only ever saw it once, but I really liked it.
Just saw my all time grand champion favorite: Staples. ‘The Most Wonderful Time of the Year’.
“They’re going baaaaaack!!!”
My heart used to soar like an eagle, late in the summer, when this commercial showed up.
