Oh I don't know. I am actually a native Arabic speaker so never needed TV shows for that purpose.
And there is one issue you will face if you want to learn Arabic watching Arabic TV Shows: Any show you pick will be in some colloquial form of Arabic and not Classic Arabic. The most popular ones across the Middle East now are in Turkish dubbed in Lebanese Arabic (Yeah :p), and seconds are Egyptian TV shows, so you will have to choose. Pretty much any country makes TV Shows in its own version of Arabic, except in Syria where they used to make historical TV Shows in Classical Arabic.
What I suggest is to watch news outlets like Aljazeera, which you can watch online for free [1]. Don't pay attention to the existing perception of Al Jazeera; they are very professional. And, relevant to our discussion, their Arabic is the best around. If in doubt, get a feeling of their editorial policies watching Al Jazeera English, then proceed to learn Arabic.
For Arabic I also recommend learning songs. I learned to read and write (but not understand anything) but the phrases I remember best are Wael Kfoury songs.
