Thanks to Christine Irving who alerted me to the article:
Rich, M. (2008) "Literacy Debate: Online, R U Really Reading" New York Times, 27 July. http://www.nytimes.com/2008/07/27/books/27reading.html?_r=1&oref=slogin
It includes a video which features a family where the parents read lots of print and the children lots of online. At time of writing there were 166 comments on it as well.
