 Passage 2:Joergen Bech, who previously worked as a developer at Innerprise Software during 1990, decided to work once again as a game programmer after dropping out of international marketing studies in 1994 and landed for the job by one of his contacts who had connection with an employee at Bethesda Softworks, who are best known for The Elder Scrolls and their most recent Fallout titles. Bethesda was interested in expanding their business to video game consoles and Joergen was hired for work on the Jaguar, due to the company receiving free Alpine Development Kits from Atari Corporation and for its superior hardware compared with other systems at the time such as the Sega Genesis and Super NES. Originally he was tasked in making a conversion of a basketball game from PC but decided to create a 2D title in order to understand the Jaguar's hardware, along with another programmer who already was familiarized with the system, after Joergen deemed the PC basketball game as a "steep learning curve" to convert, due to it being in pseudo-3D and being written on C language, which he had little to no experience with them and it was then decided that he should port Protector to Genesis, which was a conversion of Datastorm for Amiga alongside with the original authors of the game at Bethesda's Media Technology division on Denmark, with him providing the sound driver for the port, but otherwise he was not fully involved with the project and although completed it was ultimately never published due to many console, PC and multimedia titles competing for shelf space, with no prototypes of the Genesis version of Protector being found to date.
 Passage 3:As the City of Brooklyn grew, the area south of Atlantic Avenue, known as South Brooklyn, began to become developed, but the area lacked easy access to the ferry terminals in the northern parts of that city. To solve this problem, the South Ferry Company established the South Ferry on May 16, 1836 to connect Lower Manhattan to the foot of Atlantic Avenue in Brooklyn and the month-old Brooklyn and Jamaica Railroad (renamed Atlantic Avenue Railroad, later the Atlantic Avenue Railroad's streetcar line, later still part of the South Side Railroad of Long Island, now the Atlantic Branch of the Long Island Rail Road) through the Cobble Hill Tunnel. "South Ferry" was also the name of the Brooklyn landing and ferry house. In the 20th and early 21st centuries, the Brooklyn landing site served cargo as Brooklyn Piers 5 and 6, now part of Brooklyn Bridge Park
