I think you're also overestimating the amount of meaningful education kids get from TV. Language skills are learned via use. You don't actually converse with the TV. Interpersonal skills are best learned by practice. Basic facts? Maybe the TV can help here, although most kids shows don't cover anything except pretty basic stuff. Kids shows are primarily entertainment, same as adult shows.
> The average 2-5 year old is spending over 1,600 hours a year watching television. > Ratings tracking company Nielsen reported in 2014 that the average hour of television has close to 15 minutes and 30 seconds of commercials.
By their count 1/4th of each hour is commercials.
1600 * .75 / 365 == 3.3 hours per day
In what was is it not wrong?
He estimated 1/3 commercials which was wrong. He estimated 2.2 hours of TV, which is wrong regardless of whether that includes commercials and regardless of whether the commercial ratio is 1/3 or 1/4. He also went back and edited it[1] to say 2-3 hours which is still wrong, because 3.3 is not between 2 and 3.
And for the record, commercials are still TV so scaling down to 3.3 is a really bizarre choice on your part.
[1] Actually rewrote essentially the entire comment removing almost everything I responded to.
When I was a young child before I could read books, I learned tons about the world from watching Sesame Street, Mr. Rogers, and similar high-quality shows. I still spent plenty of time with my Legos, but my childhood would definitely have been worse without the programming on PBS.
