Who did a video on the Ruy Lopez?

I noticed that a lot of my opponents have been playing the Ruy Lopez lately. Curious about whether anyone knows about a YouTuber (or similar) that has done a video tutorial on the Ruy Lopez recently. Also, why do people do this? It seems like something that happens a lot in online chess is that one guy does a video on an opening and suddenly everyone is playing it.
