The music video was supposed to die when MTV stopped playing them. That was the conventional wisdom in the early 2000s, when the channel shifted toward reality programming and the primary promotional function of the short film attached to a song seemed to have evaporated. What happened instead was one of the stranger reversals in pop culture history.

YouTube launched in 2005. By 2010, it had become the primary way that a significant portion of music listeners discovered and revisited songs. The music video did not die; it migrated to a platform where it could be watched on demand rather than scheduled, and where viewership could be measured with a precision that broadcast television never allowed.

The economics changed the form. A video that needed to capture attention in the first seconds of a scheduled broadcast slot became a video that needed to hold attention through to completion in order to register on the algorithm. The best contemporary music videos are designed for a viewer who chose to watch rather than a viewer who happened to be watching, and the difference in those two postures shapes everything about how they are constructed.

The most watched music video on YouTube as of 2025 has been viewed more than eight billion times. The videos that generate that kind of traffic are not MTV-style promotional tools. They are pieces of content that exist in their own right, that people return to voluntarily, that have become cultural objects independent of the songs they accompany. Baby Shark becoming a YouTube phenomenon is strange and also a perfectly logical outcome of the form’s migration to a platform that rewards repeat engagement above all else.

The music video is not dying. It has found a new room and redecorated. Some of the furniture is the same.
