Quibi has the problem that other platforms like it have: thinking celebrities are the right way to entice people. Luminary Podcasts has the same issue. Majority of gen Z / millennial folks that I know, don't care about Trevor Noah or any of the late night comedians. They care more about famous YouTubers and TikTok stars.
If quibi was actually interested in making stuff to suit millennial taste, they should have focused on absurdist comedy, which is usually short-form anyhow. Stuff like Eric Andre or Adult Swim's "Infomercials" series ("Too Many Cooks", "Unedited Footage of a Bear" + many others that vary from amazingly memorable and funny to unwatchably awful) is exactly the kinda of stuff that I wont invest over 20 minutes in (absurd humor tends to get boring when it loses it's novelty), but whenever I find one that's really good - I'll show it to all of my friends. Having a decent budget, cast and production quality also really makes a big difference with what can be accomplished, so random absurdist youtubers usually can't provide the same experience. The fact that the Reno 911 reboot is the only thing on quibi doing well sort of confirms that the "weird comedy" genre is still underutilized.
Edit: Apparently someone has already written about this trend far more eloquently than I did: https://www.theguardian.com/tv-and-radio/2019/aug/13/how-did...
