"Why wouldn't the TV, GPS, and internet companies that use these services front the bill? "
Please explain this.
"Also, I didn't say blimps were the sole reason,they are just used in areas (like desserts) that aren't covered by other means."
Because noone ever visits deserts, isnt that right? There can't be huge towers in Africa (mostly the southern part), but that land is HUGELY populated - someone must have seen some of all those blimps. It isn't exactly common to see a blimp, you know.
And it's not just Africa, it's every developing country that can't really afford high-tech towers everywhere, that have to have flying blimps everywhere.
