See the picture for the numbers. Just look at the big table on top for the quickest results.
If you want a quick summary, most categories of vtubers are either stagnated or dropping in views, when comparing march to april; which is to be expected since the quarantines over covid are ending, so people have less time to spend on watching streamers now. The most alarming drop rate is from the ‘others’ categories, which has small corporate vtubers and indies. Twitch vtubers are also doing better growth than youtube ones, in a rough general, although they are still much smaller in their view/time rates.
I’m using the metric (vod) views/time because it seems to be the best metric we can use for comparisons. There’s no way to calculate direct hours watched without having access to data analytics from inside each channel owner or bullshit it; simply counting total views doesn’t take into account how much did they stream to get there (and they usually count small skits and music videos as well); and live viewers (on youtube) are very buggy and cut off a significant portion of that real number (for example, comparison between Miko’s twitch and youtube minecraft streams seem to indicate that 35% of her yt live viewers numbers are hidden [read the OP or the whole thread
>>2253454 for anons discussion on the possible reasons for it).
Reading and trying to compare all those ratios for each hour length would have been a pain for any of you, so that’s why I’ve already gone ahead and made the ranking tables, with ranks for inside each time length. The longer the stream time, the fewer vtubers that had any videos available to calculate. Never compare general view/time ratios of streamers who have very different stream duration averages - that’s why I painted those general rankings on right in grey. Only compare data (or ranks) from the same time length. .
Through checking their ranks in the various time lengths, you can say that Haachama is in the sole top tier; closely followed by another with Pekora, Marine, Gura; then another with various such as Aqua, Ayame, Mito, Toya; then comes another tier with vtubers like Korone, Kuzuha, Shion, Rushia; then another with Helesta, Uiha, Suisei, Miko, Subaru, Noel, Shigure, Tamaki; and son on.
Also, I had a cap of 30 videos per streamer, so it might miss a few videos for a few chuubas, but it’s good enough to get their ratios already. Video types like short skits, short amvs/covers/original songs, members only, or private were not included for the calculations. Videos analyzed for 'this month' are from the time period of 19-03-21 to 18-04-21 (~10pm jst). Streams from this recent weekend were not included.
You can see the biggest growth fluctuations with those vtubers who had some huge special stream (like 3ds, returns). They can be big rises if the special vids happened on this month period (few examples: Flare, Mori, Suisei, Fumino, Lulu, Nyanners, Veibae); or big falls if the special vids occurred on last month (examples: Gura, Sora, Okayu, Roberu, Mayuzumi, MaiR). On those cases you can see % change of one specific time length way superior than the rest for that vtuber.
Collecting all this data was a whole lot of work, I’ll likely not be doing this again, unless some very significant event happens to threaten to turn this whole current trend around. I don’t think I missed anyone too big, I left out the many smaller nijisanjis, or holostars or whoever else because I don’t have the time to include them all - but I did include a few smaller vtubers I enjoy, just out of curiosity. If you think I left out someone relevant you can try convincing me to do their numbers as well, although if they are too small I’ll just tell you to fuck off.
