TV is my ENEMY!!!!!

So for all of you that have children I hope that you can relate, ( I would surely hate to hog all the fun) but my children are CONSTANTLY turning on the TV. Anytime that I'm not looking, or am busy doing something. So in all honesty its mostly my fault, because a lot of time its a great distraction for my kids while I finish up one of my MANY ongoing projects, justification aside, I have informed my children that we will be starting a reward system at the first of the year. For the times that they do what their asked, be kind, help without asking, don't WHINE, they will be rewarded with points/ticket, and when they have something they really want to watch (if appropriate) they can redeem their tickets and watch their show, or play their video game. So I am curious if this sounds affective to anyone, or should still attempt the "IRON FIST". Let me know what you think or give me some other ideas to help the problem!!!!! Thanks
