It is shown that the nonmarkovianity measure based on autocorrelation functions is equivalent to, and easier to use than the exact Bachelier-Smoluchowski-Chapman-Kolmogorov equation. A few examples of the application of the former are discussed. It is found that nonmarkovian are: most of the processes with the stationary correlation function 
(with notable exception of the stationary Ornstein-Uhlenbeck process), fractional Brownian motions, chaotic processes, quantum oscillators, and chemical reactions.
