How Who You Know Began | A Family Game Night Tradition Since the 1970s

About Who You Know, from BoardGameGeek:

Who You Know is a fast, unplugged party game where initials spark the names. Each round, teams get a name sheet with 26 pairs of initials and race a 4-minute timer to name a real person for every pair. Celebrities, historical figures, neighbors, coworkers, and distant relatives all count. When time is up, teams reveal their answers one pair of initials at a time. A name scores only if a player on another team knows who it is. The game began as a family tradition in the 1970s and has been played across generations ever since. It plays 4 to 15 players, ages 10 and up, in 15 to 60 minutes. No screens, no phones, just fast thinking and shared laughs. -description from publisher
