Wow, I can't say I saw this one coming. The thing is, it makes perfect sense. Cisco bought Scientific-Atlanta.
If you don't work in TV, or more specifically, cable TV (as in with cable system operators), you probably haven't heard of Scientific-Atlanta. For decades, they've more or less owned the business of making equipment that transmits cable signals. Chances are pretty good that their equipment is likely at the other end of the cable from you sending out at least the analog signals. I don't know if they have the same dominance these days in the digital world.
Cisco is of course the company that makes a ridiculous percentage of the routers on the Internet. They bought Linksys a year or two ago to push into homes, and now they're going to the other place where bits go in and out of your house... your cable. That's a brilliant strategy for them because they instantly have a customer base that includes cable companies.
