On Fusion, it is often an SSI survey. You will see it on the main survey page along with Samplicious and YourSurveys. However, there is no way to know if it's Pop Rewards until you open it.
Yes, it is the one about the television shows. My main beef with this is they ask questions about what commercials there were during the program. And if you watched this program a long time ago, who remembers that? lol
But it IS fun.
