I've only read the Slate article. It's here: http://www.slate.com/id/2151538/
But researchers at Cornell University are proposing that autism correlates with the amount of time a young child views television. The slate article does stress that correlation does not mean cause and effect, and that other indoor factors might be triggering the statistical rise and fall of reported autism.
The meat of the Slate article is this:
"But the fact that rising household access to cable television seems to associate with rising autism does not reveal anything about how viewing hours might link to the disorder. The Cornell team searched for some independent measure of increased television viewing. In recent years, leading behavioral economists such as Caroline Hoxby and Steven Levitt* have used weather or geography to test assumptions about behavior. Bureau of Labor Statistics studies have found that when it rains or snows, television viewing by young children rises. So Waldman studied precipitation records for California, Oregon, and Washington state, which, because of climate and geography, experience big swings in precipitation levels both year-by-year and county-by-county. He found what appears to be a dramatic relationship between television viewing and autism onset. In counties or years when rain and snow were unusually high, and hence it is assumed children spent a lot of time watching television, autism rates shot up; in places or years of low precipitation, autism rates were low. Waldman and Nicholson conclude that "just under 40 percent of autism diagnoses in the three states studied is the result of television watching." Thus the study has two separate findings: that having cable television in the home increased autism rates in California and Pennsylvania somewhat, and that more hours of actually watching television increased autism in California, Oregon, and Washington by a lot."
The above quotes unfortunately fly in the face that correlation IS NOT cause and effect. And I hope that they were taken out of context. Otherwise I know two researchers who shouldn't have tenure.
On a side note: all of those hours of watching 'I Love Lucy', 'Leave It to Beaver', and 'Gilligan's Island' made me the logical thinker I am today? Er, right...<sarcasm>
