Lorem ipsum spotted on TV
Sometimes when you're designing a page, you need some kind of filler content to make it look more like the real thing. For my purposes while throwing together some pointless JavaScript tests, I used "blah blah". It's nothing special, and it gets the job done.
Other people prefer something a little more highbrow, and that's where you get lorem ipsum. Wikipedia does a great job of explaining it. The basic premise is: it looks plausible and manages to fill up the space without being distracting (like a bunch of "blahs" might be).
You're not supposed to see this unless you're doing the designing or perhaps are seeing pre-production materials. If you're an ordinary consumer, reader, or viewer of TV shows, it shouldn't cross your path.
This is why I really love finding it in the real world. I saw this on some cable channel a couple of years ago. I think it was Animal Planet.
They had some promo commercial running for a new web site, and obviously used a spec version of the site instead of the real thing when it was time to include a screenshot. I also like the "123456" in there.
"Eh, let's just run it. Who's going to notice that, anyway?"
Answer: I will!
