transistor in the industrial production

The transistor led to the integrated circuit which led to an entire range of products that never could have been achieved with vacuum tubes. The economic impact of this is enormous. That's one tack that you could take.

Another is the wide range of products that would never have been conceived or developed: cell phones, MRIs, home computers, small business computers, the Internet, digital cameras, and so on.

Also, you could research the human impacts: the amazing range and almost instant access to information, the entertainment aspects, education, and so on.

The replacement of vacuum triodes tubes in telephone exchanges, reducing the heater(s) energy needed. The replacements were produced on vacuum tube plugs for direct replacement, just the heater connections were not used.

What do you mean by "industrial production" ?

Thank youy to all! Now I have some hints to make a better reasearch.

The wide range of industrial production. I had to make a little research about a technlogical topic I chose and I decided this "the transistor" My teacher told me it seems not directely involved in industrial production so he changed the name of the topic.
