document: PDF subscriptions bolster revenue In 1999 SD Times offered prospective subscribers the option of receiving their issues as Adobe Acrobat PDF files . What set the proposal apart from what other publishers were doing electronically on the Web was that readers would get the entire version of the paper-including both advertising and editorial just as it looked when it was laid out and went to press . SD Times is only one of a small , but growing , number of publications that are taking on the electronic world and finding success . In the past six months alone , the New York Times , Popular Mechanics , trade magazine Electronic Buyers ' News , and the Harvard Business Review have launched digital versions of their newspapers and magazines to augment their online and print versions . The reasons are as varied as the publishers themselves . Some companies are finding that readers do n't like their Web-based versions either due to poor navigation or missing graphics and images . Others want to expand their publications nationally and internationally , but do n't want the added cost of postage and printing . Still others are looking for ways to give advertisers additional visibility and boost advertising and subscription revenues . No matter what the reason , it 's a trend worth watching
