Would you like cheese with that?!?

Why are there so many cheesy backgrounds out there?  It's like Olan Mills (or Glamour Shots, depending on which one you hate more) exploded all over the place...  I saw an advertisement for $99 muslin backgrounds, so I clicked on it:  

www.backdropoutlet.com  

The ad had a nice, basic background in the shot, but that's not what I found when I went to the website.  I was bombarded with page after page of cheesy, stupid looking backgrounds.  Who buys these things?  Who uses them?  What kind of client would want them???
