Limited Access Parents all across the country have the same complaint: kids watch too much TV. Now there may be an answer: a TV credit card called TimeSlot. Each kid gets a card with a limited amount of viewing time. The parents not only decide how much, they can block out specific times of day. It also works with video games. Sometimes the kids try to get around TimeSlot, but mostly they learn to double up their time by negotiating with one another. Parents and kids alike say using TimeSlot is not that big an adjustment.
