AT&T is consigning the Cingular name to the dustbin of history. Its wireless operator will now also be known as AT&T.

The telco kicks off a "transitioning" ad campaign on Monday and will also begin changing the livery on company buildings and vehicles. It's not saying how much this all costs, but the bill will easily run into tens of millions of dollars.

Time for a quote from Ed Whitacre, chairman and CEO of AT&T. "AT&T, BellSouth and Cingular are now one company, and going to market with our services under one brand is the right thing to do."
