Penn Center is the heart of Philadelphia's central business district. It takes its name from the nearly five million square foot office and retail complex it contains.

The Granoff School of Music is a music school in Philadelphia, Pennsylvania. It was founded by Isadore Granoff (1902 - 2000), a Ukrainian immigrant. Alumni of Granoff include Dizzy Gillespie, Sonny Fortune, and John Coltrane. Some of his students later became well-known classical, jazz, swing, big band and Latin musicians.Granoff's studio was originally in his row-house in South Philadelphia at 8th and Porter Streets, where the parlor served as waiting room, and the lessons were given in the adjoining dining room, furnished with a couple of music stands and an old upright piano. In 1928, he relocated his studio to the Presser Building at 17th and Chestnut Streets in Center City (central Philadelphia). The upper stories of that building were partitioned, and contained studios for voice and instrumentalists. It was here that his studio, originally for lessons in classical violin, metamorphosed, in the late 1930s, into the broader music school. Granoff sold the music school in 1970.

Liberty Place is a skyscraper complex in Philadelphia. The complex is composed of a 61-story, 945-foot (288 m) skyscraper called One Liberty Place, a 58-story, 848-foot (258 m) skyscraper called Two Liberty Place, a two-story shopping mall called the Shops at Liberty Place, and the 14-story Westin Philadelphia Hotel. Prior to the construction of Liberty Place, there was a gentlemen's agreement not to build any structure in Center City higher than the statue of William Penn on top of Philadelphia City Hall. The tradition lasted until 1984 when developer Willard G. Rouse III of Rouse & Associates announced plans to build an office building complex that included two towers taller than City Hall. There was a great amount of opposition to the construction of the towers with critics believing breaking the height limit would lead to construction of many more tall skyscrapers, ruining the livability and charm of Center City. Despite the opposition, construction of One Liberty Place was approved and the first phase of the project began in 1985 and was completed in 1987. One Liberty Place became the city's first skyscraper. The iconic design and spire make the complex a recognizable part of the Philadelphia skyline. Phase 2 of the project included Two Liberty Place, a hotel, a shopping mall, and a parking garage. Construction began 1988, after Cigna agreed to lease the entirety of the skyscraper for use as that company's world headquarters. Construction was completed in 1990, making Two Liberty Place the second-tallest building in the city. The two towers held their place as first- and second-tallest buildings in Philadelphia until the Comcast Center was topped off in 2007, which was surpassed in 2017 by the Comcast Technology Center. Liberty Place was received enthusiastically by critics and led to the construction of other tall skyscrapers giving Philadelphia what architecture critic Paul Goldberger called "one of the most appealing skylines of any major American city".Liberty Place was designed by architect Helmut Jahn and his firm Murphy/Jahn. The steel and blue glass skyscrapers were heavily influenced by New York City's Chrysler Building. The major influence is the spire made of gabled angular setbacks. Two Liberty Place's spire is shorter and squatter, a design influenced by the needs of tenant Cigna. In the 2000s, Cigna reduced its presence in the tower, which led to the owners converting the upper floors into 122 luxury condominiums. Below the two towers is the 289 room Westin hotel and the 143,000 square feet (13,000 m2) Shops at Liberty Place. The main feature of the mall is a round atrium topped by a large glass dome.

Five Penn Center is a 36-story highrise in Center City Philadelphia. It is part of the Penn Center complex designed by Edmund Bacon. The building was one of the tallest in the city until the high rise building boom of the late 1980s and early 1990s and is connected via underground concourse to Suburban Station, as are all buildings in the complex. It was designed by Emery Roth & Sons and Vincent G. Kling (who also designed the Philadelphia Mint).In 1986, several buildings of the Penn Center complex were renamed to their street addresses and Five Penn was no exception. Looking to get an edge up, being the largest of the Penn Center buildings and directly across Market Street from One Liberty Place, which was rising at the time, building landlords offered rental space at $16.01 a year per square foot, a marketing ploy for the building based on its address, 1601. Today, major tenants include The Neat Company, KPMG and WeWork. The building's lobby underwent remodeling in the summer of 2006.

Comcast Corporation (formerly known as American Cable Systems and Comcast Holdings), headquartered in Philadelphia, is the largest American multinational telecommunications conglomerate. It is the second-largest broadcasting and cable television company in the world by revenue (behind AT&T), the largest pay-TV company, the largest cable TV company and largest home Internet service provider in the United States, and the nation's third-largest home telephone service provider. It provides services to U.S. residential and commercial customers in 40 states and the District of Columbia. As the parent company of the international media company NBCUniversal since 2011, Comcast is a producer of feature films for theatrical exhibition, and over-the-air and cable television programming. Comcast owns and operates the Xfinity residential cable communications subsidiary, Comcast Business, a commercial services provider; Xfinity Mobile, an MVNO of Verizon; over-the-air national broadcast network channels (NBC, Telemundo, TeleXitos, and Cozi TV); multiple cable-only channels (including MSNBC, CNBC, USA Network, Syfy, Oxygen, Bravo, and E!); the film studio Universal Pictures; the VOD streaming service Peacock; animation studios (DreamWorks Animation, Illumination, Universal Animation Studios) and Universal Parks & Resorts. It also has significant holdings in digital distribution, such as thePlatform, which it acquired in 2006; and ad-tech company FreeWheel, which it acquired in 2014. Since October 2018, it has also been the parent company of Sky Group.Comcast has been criticized for a variety of reasons. Its customer satisfaction ratings were among the lowest in the cable industry during the years 2008–2010. It has violated net neutrality practices in the past, and, despite its commitment to a narrow definition of net neutrality, critics advocate a definition that precludes any distinction between Comcast's private network services and the rest of the Internet. Critics also point out a lack of competition in the vast majority of Comcast's service areas; in particular, the limited competition among cable providers. Given its negotiating power as a large ISP, some suspect that it could leverage paid peering agreements to unfairly influence end-user connection speeds. Its ownership of both content production (in NBCUniversal) and distribution (as an ISP) has raised antitrust concerns. These issues and others led to Comcast being dubbed "The Worst Company in America" by The Consumerist in 2010 and 2014.

1818 Market Street (also known as 1818 WSFS Bank Place) is a 40-story skyscraper in downtown Philadelphia, Pennsylvania, United States.

The developer, Walters Associates, which also developed the Holiday Inn at 1800 Market (now the Sonesta Philadelphia), planned a construction budget of $50 million for the property. It was the tallest building erected in Philadelphia between the completion of City Hall in 1901 and the completion of One Liberty Place in 1987, during the period of the "gentlemen's agreement", the observation of an unofficial height restriction of the top of the hat of the statue of William Penn atop City Hall that stood for 86 years. The building is the eleventh-tallest in Philadelphia.The building contains over 981,000 square feet (91,100 m2) of office space over 37 floors with six levels of parking.

In May 2015, the building was purchased by Shorenstein Properties for $184.8 million. In August 2019, WSFS Bank added their logo to the top of the building after completion of their acquisition and rebranding of Beneficial Bank, which had previously been headquartered in the building.
