"It doesn’t make sense for chocolate bars to be divided into equal-sized chunks when there is so much inequality in the chocolate industry! The unequally-sized chunks of our 6.35 oz bars are a palatable way of reminding Choco Fans and Serious Friends that the profts in the chocolate industry are unequally divided.

And in case you haven’t noticed, the bottom of our bars depicts the West African coastline. The chunks just above it represent the Gulf of Guinea. From left to right, you have Côte d’Ivoire, Ghana, Togo and Benin (terribly politically incorrect, we know, but we had to combine them to create enough space for a hazelnut), Nigeria and part of Cameroon."

Broadcast TV is already going that way. ATSC 3 requires an internet connection to get decoding keys. For your protection, of course.

That’s a great question. My guess is the bandwidth comes from bonding those extra modes and from the lower signal-noise ratio. That lower SNR means they could modulate with more sensitive but faster modes.
