Maybe I am reading this differently to everyone else, but I don't see that article as attacking the use of media in our church; it seems to me like the issue is more our ability to decipher the bible as a result of the changing way we source out information, which is in fact a valid issue. The statistic are there to show that reading of the bible in declining, even in Christian churches, and I think a church is in a dangerous place when the congregation doesn't check that what the pastors says lines up with the world of God, but just accepts what the pastor says no matter what, and people become consumers of church/christianity, as opposed to participators in church/christianity.
The other big issue that I think it neglected buy the church is the effect that media, mainly advertising has on the generations that we are growing up now (including myself as a youngish person) The crux of the message of most advertisers is that you are not good enough, you don't measure up, you need my product/service to be a sufficient person, you are inferior without it. This is the message that are young people are being bombarded with thousands of times a day; no wonder we are dealing with depression, suicide, low self esteem, self harm is epic proportions like we have never seen before in our young people. IMO that is the bigger issue created by the media, and the integration of multimedia into our society.
