The development of viscous fingering patterns has been observed from very early times to deep in the nonlinear regime for the flow of immiscible liquids in a Hele-Shaw cell. If the dimensionless viscosity contrast, A, is large, the number of fingers decreases rapidly with time after the initial pattern is established. If Aapprox. =0, all fingers grow through the entire time range of this experiment. For all values of A there is a power-law relation between the length of the longest finger and the time.
