At the same time, Facebook introduced the Mini-Feed. But the entire concept of a News Feed resulted in some very public outrage. Some users even went so far to call one of Facebook's product managers the devil.
Facebook also owns a bunch of other popular apps, most notably Instagram, which the company bought for $1 billion in 2012. With more than 400 million monthly users, that seems like a steal nowadays.

2015 was a big year for Facebook that saw its first ever day with one billion users online simultaneously. The company had figured out how to make money from mobile too, turning it into a $300 billion business.
Today, more than 1.5 billion people use the social network every single month.

Thune had been the most vocal politician to come out against Facebook after some of the social network's former contractors alleged that there had been instances in which conservative media outlets were suppressed in the Trending Topics section.
Stretch also said that Facebook's own internal investigation did not find any evidence of bias.
"Our investigation has revealed no evidence of systematic political bias in the selection or prominence of stories included in the Trending Topics feature. In fact, our analysis indicated that the rates of approval of conservative and liberal topics are virtually identical in Trending Topics," Stretch wrote.
The allegations against Facebook snowballed quickly after the original report from Gizmodo.The public pressure eventually led CEO Mark Zuckerberg to host a meeting with conservative leaders in an attempt to address and alleviate their concerns.
Thune said in a statement that he had been pleased with Facebook's response, although he did say that the reliance of Trendings Topics on human input had been greater than expected.
Thune said he hoped going forward the company would be more open in explaining its methodology.
"While the committee remains open to new information on this matter, transparency – not regulation – remains the goal, so I thank the company for its efforts to acknowledge relevant facts and its recognition of a continuing need to transparently address relevant user questions," he wrote.
