Title:
Turner_Classic_Movies

Context:
At the time of its launch, TCM was available to approximately one million cable television subscribers. 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. AMC had broadened its film content to feature colorized and more recent films by 2002 and abandoned its commercial-free format, leaving TCM as the only movie-oriented cable channel to devote its programming entirely to classic films without commercial interruption.

Question:
By what year was AMC showing commercials?

2002
