Disney+ operates on top of an expanded MLBAM (BAMTech Media [1]) platform, which has been powering all of ESPNs OTT, Playstatiom Vue, and ran HBO’s OTT offering for a while [2] (Game of Thrones). Disney also opted only to launch in the US, Canada and Netherlands today. So overall, this is still a bit of a botched launch, and the expectation absolutely should have been that they would handle the volume.
