content available online only, signaling the company's transition to a web-centric model for publication. Events, Research & Technology Marketing Throughout the 1970s and 1980s, IDG would break into the events and research spaces. In the early 1970s, it launched its Computer Caravan trade show in the US, reaching nine US cities in 11 weeks. By 1972, the Computer Caravan had a European presence as well. In the 1980s, IDG launched IDC Predictions via its subsidiary IDC, which would come to represent the company's technology research and analyst arm. The company still maintains an IDC Predictions team of analysts today that publish regular findings on the state of the worldwide technology industry. In 1991, the first IDG DEMO Conference was held in La Quinta, CA as a live forum where companies could debut their latest technology live on stage in front of crowds of technology consumers, business decision makers, and investors. The event, which would go on to be held as conferences across the US, Asia, South America, and other countries through 2015, served as the site of notable product and software launches such as Adobe Acrobat, PalmPilot, VMware Virtual Hardware, Netscape, and Salesforce. By the mid-2000s the company had established a rich online and print publication business, a trusted market research and analyst division, and a large global trade show presence - all which contributed to the growth of a database of over six million technology buyers and professionals. In 2006, IDG made this database of readers, website visitors, and event attendees available to technology marketers via its demand generation division IDG Connect. In 2010, IDG introduced the "Nanosite", an advertising tool designed as an alternative to a microsite.
