I think it means if you put the TV on all the time instead of playing with your kids when they want to. I don't know anyone who does that though.

DD watches playschool in the morning while I have a shower and do some washing etc. Then she watches playschool in the afternoon again because she loves it so much and gets excited when it comes on so I let her, lol. And I clean up before DH gets home so the house doesn't look like a bomb site, lol.
