It's not "tickets," but https://handmadehero.org/watch is live-streamed coding, funded through https://handmadehero.org/fund. I've found it educational and entertaining, and is an example of a programmer doing a "live show."

Quite a few if you include such content being bundled together with other content into a conference.

Huh? Tickets are an outdated concept on internet platforms. Space is unlimited and advertising can sustain a channel just fine.

Edit: Medium sized channel.

According to Quora [0], ad revenue from YouTube is about $1 per thousand views. I doubt that programming live streaming is mainstream enough to be sustainable from ads alone.

These metrics are totally inaccurate because different verticals pay different CPMs. Some can be much higher, but I've no idea how programming topics fares.

Even if it's 10x that, and one has 10k viewers, $100 is about one or two hours of work at a FAANG. And there's no health care coverage or free lunch for streamers.

Bear in mind that most viewers will see multiple ads during the stream, so 10k viewers could be more like 30k impressions.

Well I wasn't necessarily thinking this was being compared to a full time job, just that a channel could be self supporting, but there are ways to get close:

A strong supplement to ads is direct donations/subscriptions. If you've ever seen a YouTube/Twitch chat, people send a LOT of money that way and get their message highlighted/usually responded to for their money. It's not uncommon to see mid-tier YouTubers make hundreds in one stream but its probably the exception and not the rule.
