Magazine Ad Sales Increase In 1984, Construction Dimensions, AWCI's flagship publication, secured more advertising revenue than at any time in its then 11-year history. Ad sales grew 18 percent during the year, allowing the magazine to add columnists and expanded its reporting of industry issues. Distributors Support AWCI In the 1970s and 1980s, AWCI's distributor membership increased dramatically. Products had become more numerous and complex, and more contractors came to rely on distributors' expert services and cost efficiencies rather than stock materials themselves. "We are as proud of the services we have developed for the wall and ceiling contractors as they would be of their most prized project," said distributor Robert W. Negwer of Negwer Materials. 131
