Are there Lebanese (Arabic) reality TV shows? Can I watch them online?

Yes u can actually put a satellite (Dish Network) if ur in the U.S and subscribe to Future and LBC. They put Lebanese TV shows very often. They are also other channels that put Arabic (not Lebanese though) TV shows like MBC, Dubai, El Masreyah, Nile TV, etc. If u live in an Arabic country like Egypt, Lebanon, Syria, etc. then u can also have a satellite with the channels listed above with others like TL, Rotana (both put Lebanese programs), and many others.
