In April 2012, Instagram, along with 13 employees, was sold to Facebook for US$1 billion in cash and stock. According to multiple reports, the deal netted Systrom US$400 million based on his ownership stake in the business. One of the key contributions to the acquisition was that Mark Zuckerberg stated Facebook was "committed to building and growing Instagram independently", allowing Systrom to continue to lead Instagram. Systrom stated in an interview with Bloomberg that the pros of becoming a part of Facebook were that "we got to pair up with a juggernaut of a company that understands how to grow, understands how to build a business, has one of the best, if not the best, management team in tech and we got to use them as our resource".
Under Systrom's leadership, Instagram developed key features like the Explore tab, filters, and video. Over time, Instagram rolled out features allowing users to upload and filter photographs and short videos, follow other users' feeds, geotag images, name location, and comment on other users' photographs and short videos. Instagram allowed the development of web profiles in 2012, connecting accounts to Facebook, Twitter, Tumblr, and Flickr in 2013, an Explore tab in mid-2012, and Video in June 2013. Instagram offered 19 photographic filters; Normal, 1977, Amaro, Branna, Earlybird, Hefe, Hudson, Inkwell, Kelvin, Lo-fi, Mayfair, Nashville, Rise, Sierra, Sutro, Toaster, Valencia, Willow, X-Pro II.
