I know at least one religious family who has a tv and ones that don’t. My friends who do are the children of baal teshuva and chassidish.
Based on imamother threads, sometimes having children watch a religious children’s DVD is the most realistic way that some mothers juggle their duties in a busy household.
I think that DVDs that have religious music and teach Hebrew are great. Though I am just one person and still growing in observance.
It’s a good question. Honestly I think it depends on the family and the family’s needs. I am not sure if people are comfortable outing their tv watching, even if it’s just DVDs, IRL.
