Watch "free" channels for a year. After that year, those channels will be added to your bill if you don't call & cancel them.
When our children were ages 8-12 (3 of them), our tv broke (yes, we only had 1; we've always been frugal). DH & I decided not to buy another one - the kids needed to be out of the house & playing instead of sitting in front of the tv.
For 3 years we did not have a tv & this was before computers. DH & I loved it & strangely, the kids did not complain!

I think they just sat in front of the tv because it was there & allowed them to "zone out" on life.
No tv definitely increased our family time & interaction. We all physically moved more. No one got grouchy because others were making too much noise while their fav program was on, etc.
Fast forward 3 years, & my parents felt "sorry" for the kids & bought a new tv for us!

Graciously we accepted the "gift"! However - no cable & only educational viewing were the new rules - Discovery, History, etc. Also, no tv until it was dark outside, & no tv while getting ready for school/work in the mornings!
I recommend no tv for all families. Give it a try - it's magical! . And if an adult insists "No!", advise them they need to refocus on their main responsibility - the family, not themselves.
