Nope. The telco industry is not contracting, it's growing like crazy...just not at AT&T or VZ.
The days of selling one product and not having the ability to "own the home" are over.
Neither AT&T nor VZ has products other than service the customer actually wants.
Comcast (and soon Charter/Spectrum) has the X-1 platform. Comcast has Xfinity Mobile (with Verizon's network as its backbone). Charter will soon launch a mobile network on Verizon's network as well.
Comcast has Xfinity Home (home automation and security), Xfinity internet (its core business) and their tv product. They also own 1/3 of all of the channels currently on every tv provider's lineup, Universal Studios, and NBC. And they're just getting started in retail. They know also know how to compete.
