I heard that McKinsey has identified a new business vertical for Comcast, something fundamentally different from the businesses the company has operated for decades (more about it below). The proposed restructuring is designed to position us for this new direction. We need to be gradually shifting resources, investments and priorities away from our traditional business - that's the only way for us to survive and therefore keep our jobs (if we are lucky to survive).
Comcast's legacy businesses face increasing pressure from cord-cutting + changing consumer behavior + competition. We got to build an org capable of competing in markets where future growth and profitability may be stronger.
Still, nobody seems to know exactly what this new vertical will be. But one thing appears seems to be apparent we are preparing for a future that looks VERY different from its past and the current restructuring may be only the beginning.
