The NBA Radio Network was the official national radio broadcaster, distributed by Public Interest Affiliates (PIA), a Chicago radio syndication company, of National Basketball Association games (more specifically, a regular season game of the week, the All-Star Game, as many as 31 playoff contests, including all of the conference finals and Finals, and even the draft and lottery) from the 1990âÂÂ91 through the 1994âÂÂ95 season. NBA Radio was ultimately supplanted by ESPN Radio.
