The other religions are providing quite a challenge to the WT message. Evangelicals and even Catholics are having very attractive recruiting campaigns with music, children activities and gifts. None of this is available with the WT, people are not receptive to the door to door work; for most people is just a nuisance and the majority won't even open.
I don't think that the internet has a lot to do with the decrease, Spanish speaking are family group oriented and they get their information mostly by word of mouth.
