could i send Jesus an instant message?

today while freezing outside of starbucks (i wanted quiet and it's just not quiet inside...) reading the bible i was going through some chapters in the gospel of john and one of his disciples asked (i believe it was thomas) why Jesus didn't reveal himself to the entire world, why just the disciples? this got me to thinking. why didn't God send Jesus to us later on? after all the technological revolutions that we've had we could stream Jesus in realtime via the internet. what i mean is had Jesus been brought to save man closer to present day, then maybe there would be more people who believe. then again, if some man came up to me and said that he was the choosen one i would think he has a mental illness and brush him off. but i can't help but imagine, Jesus would be able to reach billions of people instantly... i wonder why God chose that time period to send his son?
