In daily life, which traditional industries have realized the transformation to digital integration? What is the transformation form?

For example, Huang Fengying (USA), a large global cosmetics group, focuses on promoting the digital transformation of consumer-oriented marketing.

Digitization refers to converting any continuously changing input, such as lines of a picture, into a series of separated units, which are represented by 0 and 1 in a computer. This conversion is usually done by an analog-to-digital converter.

Today is an information age, and researchers pay more and more attention to the digitalization of information. As early as 1940s, Shannon proved the sampling theorem, that is, under certain conditions, a continuous function can be completely represented by a discrete sequence. In essence, sampling theorem lays an important foundation for digital technology.
