Final answer:
Betamax struggled with economic viability because VHS provided longer recording times which made it more popular with consumers, leading to Betamax's poor sales.
Step-by-step explanation:
The Sony Betamax was a technologically superior video format to VHS, but it ultimately failed in the market. The main issue with Betamax was not globalization, innovation, or technological feasibility, but rather economic viability. VHS, on the other hand, offered longer recording times and quickly became the standard for consumers. As the market gravitated towards the VHS format, it became increasingly difficult for Betamax to compete, leading to poor sales and its eventual discontinuation.
