Final answer:
As of the last major media industry update, NBC, merged with Comcast, does not have a publicly detailed number of parks and resorts they own. The merger reduced their ownership of certain properties and, unlike Disney, their portfolio of parks and resorts is not well-known.
Step-by-step explanation:
The current ownership of parks and resorts by NBC can be tracked to their merger with Comcast. In January 2011, the Federal Communications Commission (FCC) approved the merger of Comcast, the leading cable and home Internet provider, with NBC Universal. NBC Universal is a media powerhouse that, in addition to producing television shows and movies, owns several valuable cable channels such as MSNBC, CNBC, USA, Bravo, and SyFy, but not specifically parks and resorts.
Following the Viacom merger in December 2019, Comcast-NBC Universal's profile of such properties was reduced. This suggests that compared to larger conglomerates like The Walt Disney Company, which owns numerous parks and resorts, the number of theme parks and resorts owned by NBC is not explicitly detailed post-merger, and external sources would be required for the exact count as of now.
It's important to note that these media conglomerates, which include Warner Bros. Discovery, Viacom, and The Walt Disney Company, own a significant portion of the media industry including various television networks, some of which have been listed above, which all fall under their corporate policies and decisions.
