by not so improved telephones
This question does not compare the same things. First of all, when radio broadcasting started, radio receivers were prohibitively expensive compared to disposable family income for most people. PLUS you needed to pay a license fee to even listen to your own radio. Radios got cheaper over time but not to the extent that we have seen digital equipment drop in price over the past 30 odd years. When television broadcasting started, disposable income of the average family was a lot more than when radio started so more people could actually afford a TV. When the internet started the first adopters of it ALREADY HAD a computer. All they needed was a browser and an internet connection. I had a PC in my house 10 years before the internet was easily available to me. So this question does not really compare equal things at all. Adoption of new technologies has increased over the years since say, the telephone was brought out. ALSO the question is looking a a simple number. There are MANY MORE people today than when radio was introduced. A better metric would be percentage of the population and not a static number.

No, it's an age difference of 30 years.
As a technical and scientific communicator for over 30 years, I have learned that what costs perhaps billions of dollars in inefficient communication is the assumptions people make. Each person has their own meaning of scietific or business terms. When coming together on agreements, the facilitator has to develop a sensitivity to semantics and the assumptions people make. In the process of challenging them, everyone can get on the same page through dialogue and aggrement of semantics. Generally, it is a matter of converting implicit language to explicit language. Without this process, the cost in labor and materials is substantial and immeasurable.
Dr. paul Rankin at the Ohio University is of the view that, "People are spending 85% of their working time in communication. Of this: 9% in writing 16% in reading 30% in speaking, and 45% in listening

If Elie Wiesel was born on September 30, 1928, without leap years he would be 93 years old today.
If you start when you are 30 you would probably be 32. But if you want to start at 30 you better be under 10 today.
nothing...he's dead for almost 30 years
To find the date and day 32 years ago from today, which is October 30, 2023, we subtract 32 years. This brings us to October 30, 1991, which was a Wednesday.
The Flintstones was first broadcast on 30 September 1960.
People 30 years old often drive cars. In the 1930's some people drove cars but many didn't own them. In cities they used street cars. Trains were used much more than today. Rural areas still used some horses.
