For Q4:
How can we infer that advertising was a revenue source at the
inception of the television industry?
Quote:
Sarnoff was responsible for a dominant paradigm of the television industry that continues to be relevant today: advertisers pay for the programming so that they can have a receptive audience for their products.”
And earlier:
Quote:
“Sarnoff put televisions into living rooms...”
We know that:
- Sarnoff put televisions into living rooms — i.e., he
commercialized the invention.
- He implemented a paradigm where advertisers pay for programming.
- That model continues to be relevant today.
Now, what can we logically infer?
1. Sarnoff introduced television to the public — he was the one who brought it to market.
2. At the time of that introduction, he implemented an advertising-funded model.
3. Therefore, from the very beginning of television as a public medium, advertising was a source of revenue.
Since
Sarnoff introduced TV to consumers and
his model involved advertising, the inception of the television industry = inception of the advertising model.
“inception” refers to
when television became an industry — not just the technical invention. The passage makes it clear:
- Farnsworth invented television tech.
- But Sarnoff commercialized it — he created the industry, with advertising as its revenue model.
So when the question says “at its inception”, it refers to when TV became a consumer-facing business, and that's Sarnoff's doing, with advertising at the center.
