Recovered history: 22 past broadcasts from Twitch's VOD record
Twitch's VOD record has this channel broadcasting as far back as June 25, 2026, 39 hours of airtime in total. Each one has a date, a duration and a title — viewership was not tracked at the time, so there are no viewer figures for them and none are estimated.
StreamerVitals started tracking this channel on August 14, 2026 and holds 2 finalised broadcasts and 2 days of observations so far — not yet enough to draw an honest chart. Viewership charts build from that date onwards. How recovered history works.

Times are UTC. Average and peak viewers come from periodic sampling of the live broadcast, so they are close estimates rather than exact platform figures. A stream marked “partial data” had gaps in our sampling; the unobserved time is excluded from its averages rather than filled in.
Rows marked “Archive” come from Twitch’s public VOD record. Date and duration are exact; viewership was not tracked at the time.
