In an article about a month ago at MSNBC:

Sexiness = power in porn-driven culture

Indeed, there was a time when dancing for the masses in barely there outfits was the realm of music video stars and strippers. Then the Internet and reality TV came along, providing new platforms for young women to flaunt it for a shot at fame.
In one hit prime-time series, for instance, eager young contestants perform soft-core porn dance routines in hopes of becoming the next member of The Pussycat Dolls singing group.
The fascination with being "hot" also has made its way into the workplace, where confidence is often conveyed in the way one looks and dresses.
… …
The Pussycat Dolls recently hosted a prime-time television show in which scantily clad young women performed sexually charged dance routines in a quest to be the next member of the group.

It appears that "Pussycat Dolls" is more like a "franchise" than a group. (Is there really only one group using the name?)

Maybe its purpose, quality, advertising, implementation, and effects could be best compared to the toxic offerings at McDonalds?
