I want to know the answer to the following question:
By what year was AMC showing commercials?
All the background I'm provided with is that "The network originally served as a competitor to AMC – which at the time was known as "American Movie Classics" and maintained a virtually identical format to TCM, as both networks largely focused on films released prior to 1970 and aired them in an uncut, uncolorized, and commercial-free format.". Is that enough to answer the question?
Answer: no
