I think that this is how they get you to watch.  They say something like, "see the goose that laid the golden egg", then, as you say, they keep you watching by showing you other things while continually promoting the "goose".   Similarly on the web, you often see a picture with a caption that promises to show you something interesting, then when you click on it, you see picture after picture, with commentary,  that seem to be leading up to what you wanted to see, but ten minutes passes and you still haven't gotten there yet.  I wonder if these types of sites get paid based on how long they can keep you looking at them?  Be that as it may, I share your annoyance at the practice.
