Okay, this might seem a bit like a tangent from my typical subject matter, but hear me out.
Modern life is full of media, full of influences, full of stuff that can help or hurt you and your family. If you don't deal with it with purpose, choose to let it help you and your family, it will most likely hurt you and your family.
That being said, I want to recommend something I've used for 11 years now -- DISH Network.
Why do I like it? Because first, as far as entertainment goes, it can fit into any budget that has a bit of money for entertainment. Second, you choose what comes across your TV. It is easy to lock channels you don't want you or your children (or your spouse) to see.
You can program it so you can see all the shows you really want and nothing else. DISH offers its customers a DVR which is totally cool. If there is a show you want to see you fit it into your schedule, when you can watch it.
Never again does TV have to interrupt your life. You can have the joy of it without any of the heartache. You are in charge.
Okay, I gotta tell you my two favorite shows (hey, there is no such thing as spirtual and secular categories in God's world. Everything is connected): Merlin on the SyFy Network and The Mentalist on CBS (I think on that one -- it is channel 46 on DISH).
