I thought this was curious when I saw Monday Night Football on two ESPN channels. I started thinking about the reasons why they did it. Then I found the answer:

So the main ESPN is broadcasting the game in English, while ESPN 2 is showing the same video, but in Spanish. Interesting idea. Something only ESPN could do, given the number of cable channels they own. CBS, Fox, and NBC could offer Spanish simulcasts, but they wouldn't be on equal services.
