=DoubleClick history=

DoubleClick was formerly engaged in the online media business, in addition to ad serving, meaning it helped web sites sell advertising to marketers. However, DoubleClick divested its media business several years ago, and today DoubleClick is purely involved in ad serving from the technology end uploading ads and reporting on their performance.

DoubleClick is sometimes linked with the controversy over Spyware which is installed to track users as they travel from website to website and record what commercial advertisements they view and select while browsing. However, the company maintains that it is important to understand the difference between DoubleClick s ad serving tags and the spyware/adware companies.

The companies which are most often referred to as spyware or adware represent programs external to the browser that may engage in activities such as: monitoring keystrokes or movement on the Web, examining files and programs installed on the user s hard-drive and generally behaving similarly to a virus. DoubleClick s DART, on the other hand, is well-governed within the framework of the browser. DART s opt-out policies are very straightforward and DoubleClick cookies are easy to identify and deactivate. Some years back, DoubleClick garnered some negative publicity from privacy advocates when they merged with Abacus Direct. The main problem was a possible invasion of privacy, however DoubleClick was cleared of these charges by the federal courts and state attorneys general.

In April 2005, Hellman & Friedman, a San Francisco-based private equity firm announced its intent to acquire the company and operate it as two separate divisions with two separate CEOs for TechSolutions and Data Marketing. The deal was closed in July 2005.
