Facebook

Background
Facebook is an online social media and social networking service owned by Meta. It was launched on February 4, 2004, and was the most downloaded mobile app of the 2010s. As of December 2022, there have been 3 billion active users on the platform, and is ranked third worldwide among the most visited websites.

Screen (201?-)
Visuals: There is a blue circle with a lowercase "f" on it on a white (if the device is on light mode) or (if the device is on dark mode) background. At the bottom of the screen, we see "from" and the Meta logo stacked together.

Variants:
 * Originally, just the wordmark in white was on a gradient background.
 * Late 2010s versions (until November 4, 2019) of the app had the lowercase "f" on a rounded square, with its colors inverted against a background. Under the logo features five dots that flash to represent a loading bar.
 * From November 4, 2019 until October 28, 2021, the Facebook, Inc. wordmark in was originally in place of the Meta logo, with the logos of Facebook, Messenger, Instagram, WhatsApp, and Oculus, all in, under it.

Technique: None, but 2D computer animation for the late 2010s version.

Audio: None.

Availability: Can be seen when you open the Facebook app on a tablet or a phone.
