All the FCC's captioning rules have kicked in for video that has been shown on TV and is now available on the Internet.
So during 2014, all full-length prerecorded video programming as well as all live programming--must have closed captions IF the programming was shown on television in the US with captions since September 30, 2012. If the program was shown on TV with captions since September 30, 2013, and the programs has been edited especially for Internet, then the Internet version must also be captioned.
