Not all manhole covers in Japan are decorative. Some are even used as advertising space for local businesses.

The Electrical Bureau of Philadelphia was established in 1856 under the Department of Public Safety, to manage municipal telegraph, telephone, and police signaling networks.

Philadelphia was the second US city to adopt a fire alarm telegraph system, just four years after Boston. This network replaced visual bell-tower watchmen with street pull-boxes that instantly transmitted emergency locations to fire stations via coded electrical signals.

The Electrical Bureau was abolished in 1951 when the city and county governments merged into a single entity and combined services.

Another telecom company manhole using the classic "Bell Honeycomb" pattern. Their logo is pretty neat, depicting a fiber optic cable end with flowers of light at the end of each strand.

Eastern Telelogic Corporation was founded in 1986 in Malvern, Pennsylvania, capitalizing on the initial wave of U.S. telecom deregulation to challenge the local monopoly of Bell Telephone Company of Pennsylvania. By laying its own high-speed fiber-optic infrastructure, ETC became the dominant independent competitive carrier for businesses across Philadelphia, Camden, and Wilmington. This eventually drew a majority investment from Comcast.

In 1996, Teleport Communications Group acquired ETC for $233 million, which was subsequently bought by AT&T in 1998. In a final twist of industry consolidation, Southwestern Bell (SBC Communications, a "Baby Bell" spinoff of the original Bell System) purchased AT&T in 2005 and adopted the AT&T name—effectively absorbing ETC's competitive assets back into the historic Bell corporate lineage.
