It is very difficult to make a precise estimate of an online audience. A “user”, “viewer”, “unique user”, “unique IP”, and any related term do not have a precise definition and only give estimate to the magnitude of an audience. It is difficult to detect if more people are behind one device (case often found in USA, Russia and India) or if one user is on several devices (very often seen in Norway, Sweden).

Currently, TCEC is relying on the statistics provided by Google analytics.

No matter the precise definition, the given magnitude of TCEC shows that there is a computer event that rivals in interest the top invitational human chess events. What’s more, the statistics are a precise measure that there is a trend of constant growth of the interest towards computer chess.
