Comcast is breaking up with NBCU. Why did it ever buy it in the first place?

Comcast's decision to split into separate broadband and NBCUniversal entertainment entities marks a significant restructuring in the media landscape. This move reflects a strategic shift to focus on distinct business operations and could enhance the operational efficiency of both divisions. Historically, Comcast's acquisition of NBCU was driven by the potential to create a powerful media and entertainment conglomerate, but the new separation suggests a reevaluation of that strategy in light of evolving market dynamics and regulatory scrutiny.
