Why The Merger Of T-Mobile And Sprint Is A Great Idea

By Michael Santorelli, Forbes, June 27, 2018

The pending merger of T-Mobile and Sprint presents regulators with a perfect opportunity to further propel the wireless success story in the United States. This is a story about ceaseless innovation, fierce competition, and incredible consumer gains, positioning mobile technologies at the center of American life:

 

    Pew reports that 95% of all American adults own a cellphone, with 77% owning a smartphone.

 

    Adults spend an average of 5 hours each day on their mobile devices, checking them constantly from the moment they wake until they go to sleep.

 

    Children are a growing part of the mobile revolution: Common Sense Media has found that kids aged 0-8 spend nearly an hour every day with a mobile device, watching videos and playing games. Nearly half have their own device.


    For an array of reasons, a growing share of households are smartphone-dependent for internet access, a trend that is particularly evident“among younger adults, non-whites and lower-income Americans.”

 

    It is estimated that, by next year, the time spent on one’s smartphone each day will overtake time spent watching TV, an astounding shift in a country that was once defined by its obsession with the boob tube. The shift in advertising spending, away from TV and toward mobile, has been evident for the last few years.

The mobile industry is now a critical segment of the economy, driving investment and job creation not only in the deployment and maintenance of networks, but also in device manufacturing and app development. It has been estimated that the U.S. wireless industry writ large contributes some $475 billion in GDP and supports nearly 5 million jobs. The looming transition to 5G promises to multiply these figures greatly as next-generation mobile broadband becomes the thread that ties together the internet of things, smart cities, and an untold number of other essential services that will further disrupt how we live, work, and play.

The combination of T-Mobile and Sprint will play an important role in realizing the enormous potential of 5G and in furthering disruptive innovation throughout the rapidly converging digital ecosystem. The absorption of a struggling Sprint by the unfailingly frisky and aggressively competitive T-Mobile will yield a stronger entity that is stout enough to take on the range of new competitors vying for customers in this space.

Through the Looking Glass, A Converged Reality

Gone are the days when bright lines neatly delineated discrete segments of the communications and media market. Digitization has flattened this space, lowering entry barriers to the point where it no longer makes sense for firms to compete solely within a particular slice of the market. Compounding this dynamic is how lucrative and easy it is to monetize the data emanating from consumers’ use of digital services.

Even in this converged market, it might appear that big tech firms like Facebook, which dominate the digital ad space, have little in common with a company like T-Mobile. In reality, though, they all compete fiercely for customers’ attention, positioning consumer demand as the primary force shaping the marketplace.

A desire to dominate consumer attention drives competition in our digital era. The strategies for doing so vary widely. Big tech is focused on monopolizing the online experience in order to collect as much personal information as possible, which they then use to target personalized ads. Another strategy is vertical integration, an approach that is increasingly evident in the media space.

The “Uncarrier” + A Struggling Sprint = An Even Stronger Competitor
