Prodigy was described by the New York Times as "family-oriented" and one of "the Big Three information services" in 1994. By 1990, it was the second-largest online service provider with 465,000 subscribers, trailing only CompuServe's 600,000. In 1993 it was the largest.

In 2001, it was acquired by SBC Communications, which in 2005 became the present iteration of AT&T. The Mexican branch of Prodigy, however, was acquired by Telmex.
