This is a Share Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,400 icons, all in the same style and quality.
This icon is three orbs connected with a tube. One orb is central while the two others jut out to the right, each at a different angle. A share icon is a user interface icon easily placed so that users can share content.
We’re all about sharing, so it should come as no surprise that this elegant free icon is one of our most popular downloads. We’ve taken sharing to whole new levels here at Icons8. Whether it’s stupid cat videos or pictures of your baby that nobody else really wants to see, this icon is exactly what your site, app, or neck tattoo needs. While sharing is often a great thing, we would like to remind you that even sharing has its limits. Please do not share:
That really bad picture of me where my neck is doing that thing
Erotic Twilight fan fiction
Stories about really big pimples
Your Flappy Bird high score
Everything else is pretty much fair game so download this icon and share away! ________________________________________
The History of a Share Icon
The share icon is one of the icons that really has a story. Unlike many others it needed to be created from a scratch. Why? Because a share icon should definitely be a symbol of something pretty abstract.
The share icon was specially created in 2006 by Alex King for his "Share This" plugin. In 2007 Alex started working with ShareThis company on building a new sharing tool, and the same year ShareThis bought his icon (along with the WordPress plugin code and ShareThis widget code), and also made it their logo.
But this share icon is not the only one. After that different companies created their own share icons:
Google Android uses original and its own icon
Still there is no one generally accepted share icon.
