DoubleClick, Inc.
Quick Summary
DoubleClick, Inc. was a prominent American company in the online advertising industry. It was known for placing "cookie" files on users' computers to track their browsing habits. In 1999, DoubleClick acquired Abacus Direct, which held a database of consumer buying habits. This allowed DoubleClick to link individuals' online and offline purchasing data, raising significant privacy concerns. In 2000, the company postponed its profiling scheme due to pressure from privacy advocates and investors. DoubleClick later settled class-action lawsuits, agreeing to be more transparent about its data collection and obtain permission before combining personal data with browsing history. In 2007, Google acquired DoubleClick for $3.1 billion as part of its strategy to expand into online advertising.12
