You've got to remember that "at&t" (the current one) is not AT&T, the remains of The Bell System resulting from the 1983 divestiture. SBC, which started out as a Regional Bell Operating Company named "Southwestern Bell", bought the old AT&T at firesale prices back in 2005 and assumed its corporate livery. SBC and Southwestern Bell before it, never made a secret of thinking that the 1983 Bell System breakup was a mist…
Amazing that a monopoly could eventually go bankrupt. People get paid millions a year to run companies like that into the ground. Charlie Sheen could do no worse.
The original AT&T, before SBC takeover, failed to implement number portability by the late 2004 deadline that all other wireless companies hit. They also "botched" a CRM system upgrade.
Charlie Sheen might have gotten it done better, it's hard to say. If he can listen to "the little people" telling him that problems are imminent, then maybe he could have averted AT&T's downfall.
