Ever since 1995 or so, major corporations have aligned in odd ways and created silly domain names. MSNBC is probably the most famous conflation, but ABC / Disney still does goofy things with Go.com.
It's not just domain names. Corporate America also makes up stupid URLs, obviously drawn by committee. Consider:
So let's parse this. NBC of course is the famous TV network. It could've been worse; they could've created a meaningless domain under the corporate parent, e.g. nbc.ge.com.
Anyhow, they're advertising something that they want to place under their TV show "Heroes" (which I've never seen, and do not expect to see).
So we go to nbc.com, fair enough, makes sense. And we go to a folder named "heroes" which seems to make sense, if millions of people know that show.
And now we go to a subfolder named "cisco"? All of us rely on Cisco routers, but what does Cisco have to do with Heroes, or NBC, or GE, or anything else a consumer might care about?
