We all know that witnesses go door to door in order to give bible studies. But since their message is so important to them, why don't they use all the available methods in order to reach out to the most people possible. We live in an era of telecommunications, wireless phones, internet, and so on. They surely have the financial capacities to even start their own TV stations.
Do you think they would have more success in attracting people to their religion if they used TV and Radio to spread the message?
Surely more doors would open to them when they would go door to door afterwards.
