Mount TV on the Wall

Now that  my son knows how to read and use the remote, he competes with her sister when they want to watch different  hows at the same time.  Nobody wants to watch TV at the basement because it's cold down there so they vie for remote upstairs.  Anyhow, did I tell you that my husband   wants to remove the entertainment center at our living room and wants to mount tv on wall instead?  I like the idea as it will give us more space but I just don't like the fact that I will  be losing the space where I put  the photos and other displays.  Let us see what we will come up in the coming months.
