Final answer:
Technological advancements such as the rise of music downloading have significantly impacted careers by decreasing demand for physical recordings, leading to changes in job availability within record companies.
Step-by-step explanation:
An economic change that can affect careers, particularly in the music industry, comes with technological advancements, such as new software that allows users to download music over the Internet. This digital disruption shifts the economic terrain by reducing the demand for physical recordings and subsequently impacting jobs and revenue within traditional record companies. The transition from a manufacturing-based economy to an information-based economy has also led companies to innovate or risk obsolescence.Trends like these influence both the existence of certain jobs and the nature of jobs within industries.
For example, the increased availability of music streaming services has substantially reduced CD sales, leading to downsizing or closure of brick-and-mortar record stores. Simultaneously, such technology spurs the growth of online industries, creating new career opportunities. The dynamic of shifting demands, either due to technological innovations or consumer preferences, exemplifies how economic changes can drive career transformations within the music industry and beyond.
