Do you remember the show with the flying saucer?
They went on for three seasons, and their audience grew with every episode.
The merchandising, too.
Toy robots. Lunch boxes. Fizzy candy snacks.
And, of course, a flying saucer frisbee.
Pretty soon, everyone was watching the show.
Nobody watched any another shows.
Because all they wanted to do is watch that show.
So, at the height of popularity, the network cancelled the show.
Because they were losing money on every other show.
In the end, they made a series of popular movies.
And, of course, all other movies suffered for it.
