I was searching for this video for the last 3 years.
In it a salesperson refuses to sell a tablet to the parents of a 5 year old saying that they can come back in 7 years and 12 years is the appropriate age.
What studies are there on electronics' use (age of introduction) relationships with addiction and socialization (abstinence from socialization); how to interpret those studies as a parent is there an appropriate age (a minimum tolerable or advisable age of introduction to the use of electronics) to introduce the kids to electronics?
