If I recall the first TV ad they did was
https://www.youtube.com/watch?v=wjLYPMmZfwY, which is the only one I saw -- but I saw it a lot on late-night television; probably Comedy Central or Adult Swim.
The ads were problematic in the sense that they were essentially context-free, and while "us millennials" are enticed by shows we want to stream, we're also very cautious and skeptical of heavily advertised services at a late hour.
In me, the garish palette of the ads and the name evoked MTV-style advertising of the mid-1990s, when I was much younger, and bombarded with sketchy ads for polyphonic ringtones, J2ME games, and other services for brick cellphones on late-night television: an association that made me more wary than anything else, especially since the offered content appeared decidedly second-tier.
