Cannibalization is by far the most difficult feat any established, successful company can pull off. Disney’s efforts to create a streaming video service years after Netflix and then Amazon amzn beat the entertainment giant to market will be one of the great self-attacking experiments of our time.

Now Disney belatedly plans its own streaming service.

Can Disney pull off this magic trick? Its quarterly results revealed it has no choice and that perhaps Iger should have gotten on with things sooner. Film, TV, sports, and cable all were dark spots for Disney in the quarter. Only theme parks shined.

The reliable way great conglomerates grew over time was by adding new products and buying new companies. IBM moved from mainframe to PCs. Disney dis moved from movies to parks to mega-acquisitions like Pixar, Marvel, and Lucasfilm.

Growing by embracing new technology and competing against oneself before true competitors do the job is tougher by far.

Have a good weekend, and thank a veteran for his or her service if you get the chance.
