Program: Brave (Browser)

Brave is an open source web browser, announced by the co-founder of the Mozilla Project, Brendan Eich. It aims to block website trackers and remove intrusive internet advertisements, replacing them with ads sold by Eich's company. The browser also strives to improve online privacy by sharing less data with advertising customers, instead targeting web ads through analysis of users' anonymized browsing history. Brave intends to keep 15% of ad revenue for itself, pay content publishers 55%, ad partners 15% and also give 15% to the browser users, who can in turn donate to bloggers and other providers of web content through micropayments. As of 2016, it is currently in version 0.8, and is in beta testing for iOS, Android, Windows, OS X, and Linux.
