4:3

So today I was just on Twitter and I saw this tweet.

I'm curious. Why is Justin Timberlake's Can't Stop The Feeling music video in 4:3 aspect ratio instead of widescreen?

So I looked it up. And it turns out that it is in 4:3.

Here's what the video for My Love (which hit #1 in 2007) looks like.

Notice how the sides of the video are just as wide as the ad below.

Now look at CAN'T STOP THE FEELING! (That is how it's officially typed)

As you can see, there are black bars on the left and right side of the video.

So thanks for ruining my day, Bloo.
