BIRT TubeMoguls "Brandsights" ads are the worst pre-video ads ever.

Seriously. I’m not going to link you because they are so speaker/eardrum-damagingly loud. I’ve literally run across the room to turn off my speakers, lest I annoy my neighbours upstairs. When my volume is at 2%, they’re still too loud, so I have to yo-yo my controls so that I can hear the video (which, for context, usually means a volume between 20-40%).

WHY?

I’ve never heard of them until now. That’s why.

I did a YouTube search for the ad mentioned in the OP but couldn’t find it. I got a Backstreet Boys video instead, for some reason.

It turns out they’re only on Cracked’s videos. It’s enough to turn me off of them. At least the penetration is limited.
