The technological advancement that marked the beginning of the 'Information Age' is C) Introduction of the transistor.

Here's a step-by-step explanation:

1. The 'Information Age', also known as the 'Digital Age', is characterized by the rapid shift from traditional industry established by the Industrial Revolution to an economy primarily based upon information technology.

2. The key component of this shift is the transistor. The transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is the fundamental building block of modern electronic devices and is commonly used in virtually all electronic equipment.

3. The invention of the transistor in 1947 by William Shockley, John Bardeen and Walter Brattain at Bell Labs marked the start of this era. The transistor replaced the vacuum tube for many uses and was a key factor in the development of modern computing.

4. While the telegraph, the printing press, and satellites all had significant impacts on the way information is shared and communicated, it was the transistor that truly enabled the rapid processing, storage, and distribution of information that characterizes the 'Information Age'.
