I used to work as a contractor at the Comcast Center in Philadelphia. One day my boss (at my contracting company) came by and said we were going to a meeting with Time Warner Cable execs. I reached for my coat but he stopped me; we rode the elevator up to the 16th floor where Time Warner Cable had a suite of offices ... in the Comcast Center. A year or two later they announced plans for a merger of the two companies, which was somehow and mystifyingly stopped by the FCC. Like, they'd already merged essentially.
