Can a good marketeer ignore this?
After the word "free" is the second good invention of the last years.
What is more democratic than "on demand"?
You get (almost) everything you want WHEN you want it.
The biggest success of our time (one of the biggest successes, to be more precise) is Viagra or Cialis or whatever.
It fits to "on demand"(it doesn't fit to "free", but you cannot have everything, can you?)
It is the new kind of Sex, the "Sex on demand".
You cannot have sex on Mondays for this or that, not even on Tuesdays or Wednesdays, but just on Saturdays?
And what if your biological clock doesn't want to work?
And what if biological or not it really doesn't want to work?
No problem, progress has come to your aid, now you can have "sex on demand".
Of course you also need a partner...not included in the Internet many special offers...
