Immediately after an event has completed you'll find the event in your Analytics and Recently Completed Events. Once they appear you can start gathering data from you viewers and those who are already watching on demand. However, as you can imagine, acquiring and processing data from 230,000 servers in 130 countries can take some time. Generally, it can take up to 3 hours for an event analytics to be ready completely. You'll see a notification if the Analytics for the event is still in processing as seen below:
These notifications will show up in the MyStreamSpot Dashboard for Recently Completed Events, in your Analytics dashboard Recent Events, and if you search for the specific event as seen below.
