As a coincidence, I noticed from Google Insights for Search that there was some sort of correlation between web search interests in "American Idol" (singing competition on US television) and "iPhone" (Apple smartphone). Looking at the time series graph, it appears that American Idol searches are seasonal from January to May each year, which correspond to the months which this television series is broadcast.
