> It’s not 45% of revenue expensive.

Youtubes profit margin isn't that high so it is pretty close to that, it took a long time for it to get profitable even with Google ads, unlike the digital stores that serves customers for basically nothing compared to how much revenue they bring in.

Twitch also takes around that much from streamers and they still aren't profitable since it costs more to serve the streams than they make.

Does Alphabet split out YT revenue numbers in the financial reports? The latest one listed the YT revenues, but I didn't see where the line item for YT costs was.
