what conclusions could be drawn from this table regarding the distribution and diffusion of TV over time?

number of televisions in the US grew by 187% from 1954-2015
US share of global distribution decreased as it was diffused more widely outside the US
NIR grew more rapidly than number of TVs between 1954 and 2015

1. The distribution of televisions has significantly increased over time, as indicated by the 187% growth in the number of televisions in the US between 1954 and 2015. This implies that more households have acquired televisions, leading to a wider reach and availability of TV programming.

2. The diffusion of television has expanded beyond the US, as evidenced by the decreasing US share of global distribution. This indicates that television has become increasingly popular and prevalent in other countries, suggesting a global spread of the medium.

3. The growth rate of Non-Industrialized Regions (NIR) in terms of television ownership has outpaced the overall increase in the number of televisions between 1954 and 2015. This suggests that regions outside of industrialized areas have experienced a relatively higher rate of adoption and diffusion of television technology.

Overall, these conclusions show a trend of increased TV distribution and diffusion globally, with a particular emphasis on the expansion of television outside of the US and in non-industrialized regions.
