but the one that stands out is the live event channel. Something occurred to me while thinking about the potential of a live 4K channel.

First, I don't think this currently exists and it would have massive appeal. Think about UFC, WWE and other pay per view sporting events. If you spent the extra money on a 4K TV and wanted to watch the massively anticipated boxing match between Floyd Mayweather and Manny Pacquiao, would you pay a little extra for the 4k version? I believe people absolutely would. This channel is expected to launch in 2nd quarter and if marketed properly could be a massive business by itself. Seems they would be first to market.
