I’ve been puzzled for weeks about the advertising blitz for Cingular Wireless. I knew they were the hellspawn of some universally despised behemoth telcos, I just didn’t know which ones. I finally got off my butt and did the 5 seconds of research it took to discover that they are the product of a joint venture between BellSouth and SBC. (A reader sent along a note that Pac Bell Wireless is also part of Cingular. Blech.)
