When the Lord appears, will it be televised, only God knows. But.... The glory of the Lord will be so bright that it will draw everyone's attention and those who aren't ready will either be running or hiding, as by that second it will be too late for them to repent and turn to Jesus, so saying that, it might be televised, but everyone will be in the moment, they are either going to be rejoicing or terrified, including media, actors in their acting sets, sports stars in the football, tennis, everyone, so I don't think there will be someone on the other end of the camera recording for long and I don't think people are going to be watching their tvs for more than a 30 seconds either. It will be like a loud boom that grabs everyone's attention, except it will be trumpets sounding, and the wonderful glory of Jesus shining. Who knows maybe the sound of the trumpets will even shatter the TV screens lol.
Ah well we will find out on that great day. :)
