Its miniaturization and efficiency made possible the development of many subsequent electronic devices like computers, mobile phones, and various other modern electronics. Automobiles were invented much earlier. Television was an important invention but did not have the same foundational role for other inventions as the transistor. Hearing aids are a specialized application and not a foundational invention for a wide range of other inventions.
