I want to know the answer to the following question:
What was a leading factor in the 16:9 aspect ratio being chosen?
All the background I'm provided with is that "Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format.". Is that enough to answer the question?
Answer: yes
