The Oligocene (symbol O_G) is a geologic epoch of the Paleogene Period and extends from about 34 million to 23 million years before the present (33.9±0.1 to 23.03±0.05 Ma). As with other older geologic periods, the rock beds that define the period are well identified but the exact dates of the start and end of the period are slightly uncertain. The name Oligocene comes from the Greek ὀλίγος (oligos, few) and καινός (kainos, new), and refers to the sparsity of additional modern mammalian species of fauna after a burst of evolution during the Eocene. The Oligocene follows the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period.

The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion of grasslands, and a regression of tropical broad leaf forests to the equatorial belt.

[presently Belarus]) is a video blogger, co-owner and director of operations of a wine retail store, and an author and public speaker on the subjects of social media, brand building and e-commerce. Vaynerchuk immigrated to the U.S. in 1978, and after graduating from Mount Ida College in Newton, MA, transformed his father's Springfield, NJ liquor store into a large scale retail wine store named Wine Library, and in 2006 started the video blog Wine Library TV, a daily internet webcast on the subject of wine, which launched his career of internet celebrity.

He has been featured in The Wall Street Journal,GQ, and Time, appeared on Late Night with Conan O'Brien and Ellen. Vaynerchuk has been described as "the first wine guru of the YouTube era", "the wine world's new superstar", and by Rob Newsom, a Washington State wine maker, "outside of Robert Parker, probably the most influential wine critic in the United States". In the July 2009 Decanter publication of "The Power List" ranking of the wine industry's individuals of influence, Vaynerchuk placed at number 40, citing that he "represents the power of blogging".
