Partners 20 of 69,331
It's still not much in plain numbers but still double as much as before.

Some people are switching or at least creating an account on @joinmastodon due to @elonmusk buying Twitter.
I thought it would be interesting to check how many @Twitch affiliates and partners link to their Mastodon account:

It's been nearly 2 weeks so lets look at the stats again to see if something changed. Looks like the noise was bigger than the action as not many have switched away from Streamlabs.
As lots of people have asked about data for active accounts here is the list for the current status on accounts which streamed at least once since 2021-11-18

Today I took a look at @streamlabs vs @StreamElements tipping usage by @Twitch partners and affiliates:

This kind of information is not available to 3rd parties. The best you could do would be to break it down by "broadcaster language", basically the language the user sets in their dashboard.

Q3 2020 is already over so it's time for @Twitch stats:

* Not all affiliates or partners have their sex categorized, mostly just the ones with the most viewers (~54k accounts)

Twitch currently has 711,836 affiliates and 38,883 partners, all while having 1,518 staff accounts.

After probing a lot of Twitch partners the news are in:
Twitch users often say that females have it easier... males however are still 3/4 of partner channels.

I did not but I was able to use my broadcaster type changelogs to extrapolate the numbers from 2017-07 going forward.

Today marks the 2 year anniversary of Twitch name changes.
I'd like to celebrate this with some stats:
More than 7,786,033 users changed their name, 1,013,448 more than once.
In related news there are 507,267 affiliates and 35,580 partners while Twitch has 1260 staff accounts.

Partners can have different contracts in regards to their revenue share:

I just noticed it's been over a year since my last little stats Tweet.
Here is an update on the current affiliate & partner numbers:
There are currently over 372,574 affiliates and over 32,831 partners on Twitch.
6,441 affiliates got partnered and 695 left the affiliate program.

Some Twitch users often say that Twitch staff members are more biased towards woman so I thought I would check which channels are the most subscribed ones by staff.
Turns out that sub numbers are dominated by male streamers and not female ones.

There are currently more than 90,560 affiliates and 23,531 partners.
Over 461 affiliates got partnered. 21 users stopped being an affiliate

Twitch name changes are 6 months old today.
Some stats: 3,801,723 users changed their name, 94,178 more than once.
