There are some things we have to keep in mind, the first of which I'll call "size." I'm going to quote Wikipedia:.
About
Comcast:
It is the second-largest broadcasting and cable television company in the world by revenue (behind AT&T), the largest pay-TV company, the largest cable TV company and largest home Internet service provider in the United States, and the nation's third-largest home telephone service provider. Comcast provides services to U.S. residential and commercial customers in 40 states and in the District of Columbia. As the parent company of the international media company NBCUniversal since 2011, Comcast is a producer of feature films and television programs intended for theatrical exhibition and over-the-air and cable television broadcast, respectively.
Comcast owns and operates the Xfinity residential cable communications subsidiary, Comcast Business, a commercial services provider, Xfinity Mobile, an MVNO of Verizon, over-the-air national broadcast network channels (NBC, Telemundo, TeleXitos, and Cozi TV), multiple cable-only channels (including MSNBC, CNBC, USA Network, Syfy, NBCSN, Oxygen, Bravo, and E!, among others), the film studio Universal Pictures, the VOD streaming service Peacock, animation studios (DreamWorks Animation, Illumination, Universal Animation Studios) and Universal Parks & Resorts. It also has significant holdings in digital distribution, such as thePlatform, which it acquired in 2006 and ad tech company FreeWheel, which it acquired in 2014. Since October 2018, it is also the parent company of mass media pan-European company Sky Group, making it the biggest media company with more than 53 million subscribers in the U.S. and Europe.
Revenue: US$103.56 billion (2020)
Total assets: US$273.69 billion (2020)
For comparison, let's look at the
Walt Disney Company:
The company is known for its film studio division, The Walt Disney Studios, which includes Walt Disney Pictures, Walt Disney Animation Studios, Pixar, Marvel Studios, Lucasfilm, 20th Century Studios, and Searchlight Pictures. Disney's other main business units include divisions in television, broadcasting, streaming media, theme park resorts, consumer products, publishing, and international operations. Through these various segments, Disney owns and operates the ABC broadcast network; cable television networks such as Disney Channel, ESPN, Freeform, FX, and National Geographic; publishing, merchandising, music, and theater divisions; direct-to-consumer streaming services such as Disney+, Hulu, ESPN+, and Hotstar; and Disney Parks, Experiences and Products, a group of 14 theme parks, resort hotels, and cruise lines around the world.[
Revenue: US$65.388 billion (2020)
Total assets: US$201.549 billion (2020)
By most standards these two corporations are huge.
Now let's take a look at
ViacomCBS:
The company's main assets include the Paramount Pictures film and television studio, the CBS Entertainment Group (consisting of the CBS television network, television stations, and other CBS-branded assets), domestic networks (consisting of U.S.-based basic and premium-tier cable television networks including MTV, Nickelodeon, BET, Comedy Central, and Showtime), international networks (consisting of international versions of domestic ViacomCBS networks as well as region-specific networks), the company's streaming services, including Paramount+ and Pluto TV, and the Simon & Schuster book publisher (sale to Penguin Random House pending in 2021).
Revenue: US$25.29 billion (2020)
Total assets: US$52.66 billion (2020)
When I look at these numbers in the context of Comcast's NBCU merger regulatory history, I really don't see a smooth approval process for acquiring ViacomCBS. It seems like it would be a rough road even for Disney.
Handing off control of WarnerMedia to Discovery creating a combined company worth of $100+ billion forcused mostly on content is one thing. But combining Comcast and ViacomCBS would raise many red flags, maybe too many.
Just my opinion, of course.
