Old-style toys are better.
Children’s toys and books sell because they engage. So any “doodad” that catches the eye of a kid, or his parents, helps to generate sales. Nowadays, lots of kids’ toys make noise or flash lights – even board books and traditional games like Monopoly have electronic versions. And screen-based entertainments have proliferated; apparently 3/4 of kids have their own cell phone or tablet by age 4.
