South By Southwest (SXSW) has launched a free, on-demand service, SXSW On, that will feature performances from the festival, original programming, and interview, among other things. The service will be available on YouTube, and on Roku in the U.S., Canada, UK, and Ireland. This will be the first time SXSW will be featured on smart, streaming devices. The SXSW festival and conference will kick off later this week.
