Facebook's sentimental "Look Back" videos generated tremendous response on the social network with 200 million users creating and watching their top social networking moments over the years.

Facebook celebrated their tenth year anniversary last week by introducing a new feature called "Look Back" that gave its members a glimpse of their top social networking moments in a beautiful one-minute video. The announcement was made by Facebook chief operating officer Sheryl Sandberg during a Q&A session at the Goldman Sachs Technology and Internet Conference, Tuesday.

"It was amazing," Sandberg said of the response to Look Back, CNET reports. "Almost 200 million people watched [their Look Back video], and 50 percent of people [about 100 million users] who watched their own video, shared it. It ... showed the power of the Facebook brand."

The Look Back videos went viral on the timeline of users, as the social media giant notified its users about the feature. Facebook also granted access to a grieving father from Missouri, who requested a for his late son's Look Back video.

The short videos kept trending on the timeline since they were introduced last week on February 4. But the frequent appearance of the videos on the site also became a cause of annoyance for a few, resulting in a series of memes making the rounds.

If you haven't been on the social network for over a week, a Look Back video is Facebook's sentimental way of reminding its members of the photos and moments shared on the site since the beginning. The short video highlights the most popular videos and posts from the user over the years. But those statuses and pictures were chosen by the social network, so not many users were happy about the choice. But Facebook also gave an edit feature to the video so users can change the photos that they want on their Look Back video.

You can still make your Look Back video and share it with your family and friends.
