Paper finds that TV may boost performance on standardized tests

The Wall Street Journal on why television may historically have boosted academic achievement.

Specifically, television started up after WWII, then stopped expanding between 1948 and 1952 for regulatory reasons. Comparing the later test scores of those who had access to TV during their early years to those who did not, they found the former group did noticeably better on these standardized measures.
