I'm not sure how to tackle how your examples because to me, reading them aloud, they seem inane in their description and questioning--persnickety as to why doesn't the consumer stick to channels and shows they can understand, as if it might be their fault you are noticing more of these Spanish spots--but as a whole:
Comcast / Cox / Verizon any company along these lines (not so much the satellite providers, though); they know their demographic, very well, and if they can better advertise to a very large group of their consumers (the Latino market, and it is a massive market in South Florida, all along the Eastern coast, and a majority of the Sunbelt) then they will run advertisement spots that will make their targeted audience feel more at ease, and utilizing their native language is an effective tool to instantly capture their attention (assuming the consumer who pays for cable subscription watches more channels than the eight Spanish channels that is afforded to them).
Spanish is the unofficial second-language of the US (being that the first "unofficial" language is English) and as those consumers want to be as educated as the rest of us, it makes sense that some smarter companies have bought time on channels such as Discovery and ESPN that run maybe 1-4 Spanish language commercials in a 24-period, just to catch the attention of a wayward surfer.

The perfect example of this trend may be that Comcast commecial where the young girl is on the phone talking to the company operator, guiding her "abuelita" as to how to set up the newly-installed cable package, and just as she falters in translating instructions towards her elderly grandmother, the operator states the phrase in Spanish, as if to say, "we're a family, nation of one, people, etc.", I don't know.
