https://LBRY.io - "Watch, read and play in a decentralized digital library controlled by the community"
The LBRY Beta launched a few days ago. Access codes can be obtained from their slack - https://slack.lbry.io - and you get a few credits to play with.
If anyone wants my referral link to register for access PM me for details.
Edit: (This isn't actually an access code just a normal ref link to the registration page).
There isn't much content available yet, but I streamed a 10min music video all via blockchain with only 1 little hickup. Quality was great.
LBC (their "coin") was listed on Bittrex today.
LBC is currently CPU mined for anyone interested. I'm mining on a few machines and have found a number of blocks so far.
