Question 1

Where does the quadrant channel history come from?

Accepted Answer

Branzly stores a daily snapshot of subscribers, views and uploads for every channel it tracks, plus the date of each earnings report and every channel name we have observed.

Question 2

How are the earnings over time calculated?

Accepted Answer

Each day we take the increase in lifetime views and apply our RPM range to it, so the earnings line shows what the new views of that day were worth in advertising revenue. Figures are estimates, not verified payouts.

Question 3

Why are some earlier dates missing?

Accepted Answer

Daily snapshots start on the day a channel was first indexed by Branzly. YouTube does not publish historical snapshots or past channel names. For some channels the subscriber chart also shows real counts from archived copies of the YouTube channel page; we never fill gaps with invented numbers.
