They did. It was called Major League Baseball Advanced Media, aka MLBAM, aka BAMTech, aka Disney Streaming.The big picture being?.. That Disney is going to revolutionize something here?
If so, yeah, I'm missing it because anything home-grown from Disney requiring any sort of major technical infrastructure seems dubious at best but who knows, maybe they'll acquire someone for something other than IP and that'll fix things.
But yes, you're vastly missing the big picture. My American Express card includes a gym membership, a streaming service, loyalty status at multiple hotel chains, Walmart+ (which includes a second streaming service), and all sorts of other incidental benefits. My internet package with Comcast includes Peacock, which includes WWE Network. It's not 2008 anymore. Before long, Netflix will be the only streaming platform that *doesn't* include other services and benefits.
