On February 4, 2004, the United States Defense Advanced Research Projects Agency (DARPA) canceled its LifeLog research program, which had been launched in 2003. The program was designed to explore technologies capable of collecting and organizing large amounts of personal data to create a digital record of an individual's daily life.
According to DARPA program descriptions, LifeLog aimed to track and link a wide range of data sources including communications, locations, purchases, media consumption, and other digital activities in order to build a searchable timeline of a person's experiences and interactions.
The program generated public debate and criticism from privacy advocates and civil liberties organizations who raised concerns about the potential surveillance and data collection implications of such a system.
DARPA announced on February 4, 2004, that the LifeLog program would be terminated and that no further work would continue under the project.
On the same day, February 4, 2004, a social networking website called Thefacebook was launched by Harvard University student Mark Zuckerberg along with several classmates. The website initially allowed Harvard students to create profiles and connect with other users within the university network.
The platform later expanded to additional universities and colleges before opening registration to the general public in 2006. The service was later renamed Facebook and grew into one of the largest social networking platforms globally.
