(Twitter also generates revenue from data licensing and other sources, so even the difference between these two figures can't be chalked up to subscriptions alone.) Of course, it's impossible to tell from third-party data exactly how much consumer spending in the Twitter app was directed at Twitter Blue specifically, as Twitter also offered in-app purchases for "Ticketed Spaces" — that is, paid entry into a special event as a part of Twitter's live audio streaming product. But we can estimate that Ticketed Spaces revenue was only a small fraction of that total, if anything at all, as Twitter found that feature had seen so little adoption it decided to shut it down last month, Twitter recently confirmed to TechCrunch.
