Yes, in previous years, the Austin Convention Center was the only venue for SXSW Conference daytime programming. However, as the event has grown over the last few years, we have moved to multiple campuses to accommodate this growth.
The concept of a ‘main venue’ no longer exists for the SXSW Conference. All campuses are created equal. If your session has been scheduled at another venue (that is not the Austin Convention Center) this is because the venue you have been assigned is the venue where we are hosting all sessions related to the track / topic of your session and where your session’s intended audience will likely be.
