They should have never been combined, wireline, wireless, entertainment and all completely different businesses with different skillsets.
They need to be separate businesses to allow each to flourish and grow.
The wireline is the foundation, all of these businesses and deriatives depend on wireline for data and communications transfer. Stephenson thought all wireless communications, in his own words, "just jump from tower to tower without need of cable".. THAT was one id10t nerd accountant and his desire to be the "grand poobah" (Flintstones reference) is what hurt this company.
Usually there is only a split because there are so many talented exec's and they need to split so they can have more presidents and ceo's and cfo's...
This is NOT the case now, but, entertainment and wireless and wireline should have never been combined and it's never too early to start fixing what is broken.
