Learn Greek Online!

I was wandering if trade/brand names etc are inflected.  What prompted me to ask this is the following:  There is a Greek TV series called "Η Ζωή της Άλλης".  On the web I have seen advertised "το τελευταίο επεισόδιο της Ζωής της Άλλης" (The final episode of "The Life of Another").  So in this sentence the name of the program itself is being inflected.  Is this standard practice?  Or would you ever say:  το τελευταίο επεισόδιο της <<Ζωή της Άλλης>> which sounds grammatically incorrect.

Thanks in advance for any help.
