Answer:
computers less expensive.
radios more portable.
televisions more widely available.
Explanation:
The transistor made "computers less expensive; radios more portable; and televisions more widely available."
Transistor was an invention made in 1947; it was made to replace the vacuum tube due to its smaller size, less power consumption, and more reliability.
Hence, by 1954, the transistor was used on the radio. It makes the radio more portable, increases broadcast accessibility, and less costly compare to vacuum tube radio. It is also used in televisions in later years, which makes it more widely available. Then it is also used in the making of a computer's CPU, thereby making it less expensive than the previous computer generation.
