Concurrent Viewers
Concurrent viewers is the number of people watching at the same moment — unlike cumulative viewers, it reflects both real-time momentum and server load.
How does it differ from cumulative viewers?
Cumulative counts everyone who dropped in at any point; concurrent is how many are there at a given instant. A broadcast with 100,000 cumulative but 500 concurrent means people looked in briefly and left — the content didn't hold them.
What should you look at?
The peaks and troughs of the concurrent curve. Seeing which product drew people in and where they left gives you the evidence for how to order the next broadcast.
Frequently Asked Questions
Q. Will a high concurrent count break the stream?
Not if the platform is built for large concurrency. If you're planning a big broadcast, confirm the load ceiling beforehand.
Q. Which one should be the KPI?
Use cumulative for reach, and concurrent plus average watch time for how well the content actually holds people.
