The Big Brother E-Z underwear radio club was a promotion for both the underwear brand and the radio show starring Big Brother Bob Emery, who began broadcasting children's programming in Boston during the early 1920s. The Big Brother Club was born shortly afterwards and became a very popular nighttime show for children to listen to stories and music. Kids could apply for membership and receive a card and a button, and were encouraged to do good deeds. E-Z underwear for boys was manufactured and sold by E-Z Mills, Inc.
