Idea of Google Groups Filled Icon
It's an icon for Google Groups. It shows a talking bubble like you would have to denote someone speaking. The bubble is square-shaped with three people depicted on the inside of it. The people have round heads that float above a half circle which faces downward.
This is a Google Groups 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 13,900 icons, all in the same style and quality.
