As I've said before, and as my parents used to tell me when I needed to learn the facts: look it up. I haven't made ridiculous claims that have no basis in reality; you have. The burden of proof is on you.
You're the one saying radio attempted to "kill off digital." It's clearly documented that radio companies have been involved in digital technologies for 30 years. I've already given you very clear and accepted examples of how. The onus is on you to show where my documented examples are wrong.
