"Young adults had the highest uninsured rates before the Affordable Care Act and have seen the sharpest drop in uninsured rates since 2010," Erik Martin, policy advisor for the White House Office of Science and Technology Policy, wrote in a blog post on Thursday.

Twitch has 9.7 million daily active users and each person on average watches 106 minutes of video per day. This is a highly engaged community that the White House is hoping to attract.
ESports is also big business. Revenues from eSports are set to grow 51.7 percent year-on-year in 2016 to $493 million, and eventually hit over $1.12 billion in 2019.
