The latest study, in the U.S., looked at whether there was a link between rising rates of autism and the increasing availability of children's TV, videos and DVDs.
The research team concluded that the results were "awfully suggestive" of a link between watching TV and autism.
As they were unable to obtain any statistics on toddlers' TV habits, they used rainfall levels in different parts of the country to help estimate how much time children spent playing outdoors.
They found that the wettest areas, where, presumably, children spent more time indoors watching TV, had the highest rates of autism.
Dr Michael Waldman, who led the study, said: "We ran the tests a number of different ways, and basically, every way we run it, we get the same thing. If it rains more, autism goes up. If it rains less autism goes down."
