We don't have to trash 150 bazillion radios, just 800 million.

I think I mentioned my retailer visits when we had lunch some months 
ago. The bottom line is that there's no market for the system. Every 
retailer in my area who has carried current receivers has had 100% of 
them returned, they say. I think it's more like 99.9999% because I 
kept mine. They don't seem to be factoring in the radio station folks 
who are close enough to get an RF burn and receive the signal.

In a perfect world, you're right. However, we'd need to get 
proprietary information from iBuckuity, then get them to approve a 
modern technology design that could be sold for under $50. Rumor has 
it that the per receiver fee is $40.

This whole concept is riddled with deception and PR puffery. The 
other problem that's beginning to be noticed is that we'd jump from 
just under 15,000 stations to about 22,000. There isn't an 
advertising market for that many stations. I'm considering a 
secondary to be a station. I think we all remember the years of 
complaints about Docket 80-90 that added many more stations to 
already glutted markets.

The intellectual property is owned by iBuckuity. To do what you're 
proposing would require a different system, from beginning to end. 
Again, for an entrepreneur to take an interest he or she would have 
to ignore the current aggressive apathy on the part of consumers 
toward the whole issue. The second Bridge Ratings report showed more 
people knew about the system and fewer were interested than in the 
first one. It seems the more they know, the less interest they have.
