You Tube earns advertising revenue from Google Ad Sense, a program which targets ads according to site content and audience.
The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as You Tube Red, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users.
On August 10, 2015, Google announced that it was creating a new company, Alphabet, to act as the holding company for Google, with the change in financial reporting to begin in the fourth quarter of 2015. You Tube primarily uses the VP9 and H.264/MPEG-4 AVC video formats, and the Dynamic Adaptive Streaming over HTTP protocol.
Previously, viewing You Tube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser.
According to data published by market research company com Score, You Tube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010..
