Economy of Long Island
Long Island's commuter towns are well known for supplying skilled labor to more urbanized places, but its two counties have their own factories, offices, schools and other workplaces, employing more workers than those who commute to distant jobs. It is distinctly noted for its absence of Fortune 500 companies in the NYC metropolitan area, the remaining vestiges of its once dominant aviation industry and its reliance on professional services. the government sector and big-box stores for regional employment.
Affluence
The counties of Nassau and Suffolk have long been renowned for their affluence and high standard of living. This affluence is especially pervasive among the hamlets and villages on the North Shore of Long Island as far as western Suffolk, the extreme eastern South Shore and several wealthy pockets along the South Shore further west. However, nearly all of Long Island is quite expensive to live on by national standards.Long Island is home to some of the most expensive mansions in the country. In 2005, the most expensive residence in the country was Three Ponds in Bridgehampton. Several of the nation's largest private residences are also on Long Island, including financier Ira Rennert's, Fair Field, in the Hampton's hamlet of Sagaponack and the country's second largest home, Oheka Castle. Long Island is home to the luxury communities of the Hamptons, Cold Spring Harbor, Dix Hills, Centerport, Huntington Bay, and Lloyd Harbor in Suffolk County, and Hewlett Bay Park, Cove Neck, Oyster Bay Cove, Laurel Hollow, Sands Point, Roslyn, Brookville, Old Brookville, Upper Brookville, Lattingtown, Matinecock, Muttontown, Hewlett Harbor, and Manhasset in Nassau County.
Aviation industry
Long Island industry has long benefited from its proximity to New York City. During the 1930s, the island developed an aviation industry, and until about 1990 was considered one of the aviation centers of the United States, with companies such as Grumman Aircraft having their headquarters and factories in the Bethpage area. Grumman was long a major supplier of warplanes for the U.S. Navy and the Marine Corps, as seen in many movies. Prominent WW-II Grumman aircraft included the Grumman F4F Wildcat and Grumman F6F Hellcat fighters, and the Grumman TBF Avenger torpedo bomber. Grumman was also prominent in the US space program, being the producer of the Apollo Lunar Excursion Module.In their early decades, aerospace-related companies were concentrated on Long Island, especially in eastern Nassau County in the Bethpage area. Over the years, the industry also diversified to other locations. The Sperry Gyroscope company did very well during WW-II as military demand skyrocketed; it specialized in high technology devices such as gyrocompasses, analog computer-controlled bombsights, airborne radar systems, and automated take-off and landing systems. These became jumping-off points into the multibillion-dollar annually avionics business. During the Cold War decade of the 1950s, part of Sperry Gyroscope was moved to Phoenix, Arizona. This was to try to preserve parts of this vital defense company in the event of nuclear warfare. Both on Long Island and in Arizona, Sperry continued to excel in avionics, and it also provided avionics systems for such NASA programs as the Space Shuttle.
The Cradle of Aviation Museum illustrates and celebrates Long Island aviation.
Long island is home to major divisions of the aircraft systems manufacturer, B/E Aerospace. Their products range from cabin lighting assemblies to aircraft lavatory systems.
Science and engineering
Long Island, has played a prominent role in scientific research and in engineering. It was once the home of the Grumman Aircraft factories where all the Apollo program Lunar Module spacecraft were built; and it still is the home of the Brookhaven National Laboratories in nuclear physics and United States Department of Energy research, as well as physics and astrophysics research projects at Stony Brook University. Additionally, Cold Spring Harbor Laboratory, is a leading government-funded research laboratory specializing in biomedical education and research. All of these continuing facilities make Long Island a leading high-technology research area for government research.In the mid to latter part of the 20th century companies such as Sperry Rand and Computer Associates, headquartered in Islandia, made Long Island a center for the computer industry. Gentiva Health Services, a national provider of home health and pharmacy services, was once headquartered on Long Island, but is now based in Atlanta, Georgia.
Long Island was home to the first Trans-Atlantic radio broadcast, from Rocky Point, New York to Paris, France.
Agriculture
Long Island, NY is rich in farming history and features many produce farms located on both the North Shore and South Shores. Because the western and central regions of the island are now largely devoted to residential use, the East End of the island is now the primary agricultural area of Long Island.East End farms and farmers' markets are the major providers of Long Island's remaining supplies of locally grown fruits, berries, vegetables, poultry, and dairy products. Some farms offer pick-your-own peaches, apples, and pumpkins.
This has become a traditional spring, summer, and fall outing for many Long Island residents. The island also still has a considerable area and resources, even in Nassau County, devoted to landscaping horticulture.
Long Island wine
In little over quarter of a century the Long Island wine industry has grown from one vineyard to of vines in thirty wineries. The island's maritime climate, geography and soil characteristics provide good winegrowing conditions.The Long Island wine region formally encompasses all of Nassau County and Suffolk County, but most island vineyards are located on the North and South Forks. Some of the vineyards can grow European varietal grapes, while others concentrate on hybrid grapes that are better-adapted to North American conditions of climate and pest resistance. Some examples are: Palmer Vineyards, Macari Vineyards, Bedell Cellars, Pindar Vineyards, Wolffer Estate Vineyard and Martha Clara Vineyards.
News and media
Long Island is the home of several newspapers and radio stations. Newsday has one of the largest circulations of all U.S. daily newspapers. The Long Island Press is a weekly paper begun in 2003. There are a few specialty newspapers such as the Long Island Business News and there are several weeklies that cover smaller community news and current events in the Long Island Communities. News 12, once owned and operated by Cablevision System Corp, is one of the primary Long Island TV cable news channels. News 12 also provides local news separately to Brooklyn, Westchester and New Jersey to each of the areas it serves through its cable delivery services. In addition, the metropolitan area is served by PBS' Long Island affiliate, WLIW, with the 3rd largest public television viewership in the U.S.Tourism
Tourism in the area is primarily focused on the summer season and on the East End, with visitors attracted by the natural environment, parks and beaches in Long Island. The North fork on the east end of Suffolk County is known for its fishing villages, tourist towns, ferries to Connecticut and its neighbors, and for the area's wineries. The South fork has similar tourist attractions including golf, equestrian, boating, surfing, and fine dining in the Hamptons and Montauk. Patchogue is also host to the Patchogue Theatre for the Performing Arts, which is also the official home theater of the Atlantic Wind Symphony.Villages are additional tourist destinations on the Island. Some tourism is local Long Islanders visiting nearby friendly villages. Examples of villages that attract surrounding communities include Huntington Village, Northport Village, Islip Hamlet, Port Jefferson Village, Sayville, and Cold Spring Harbor in Suffolk County. Roslyn Village, Great Neck, The City of Long Beach, The City of Glen Cove, Massapequa Park and Rockville Centre, Garden City are popular Nassau County Villages. The Long Island Convention and Visitors Bureau provides information about tourism on Long Island.
Other industries
continues to be an important industry, especially at Northport and Montauk. In fact, following the demise of the oyster industry in the 1950s when oysters had all but disappeared, through concerted efforts by New York state, local government and the resources of Cornell Cooperative Extension’s Marine Research Facility in Southold to develop new technology in support of the sector, Suffolk County, in particular, has revitalized the oyster industry through oyster farming. As of 2018, there were 82 registered permits issued for oyster farming, according to the state Department of Conservation.Since World War II, Long Island has become increasingly suburban and, in some areas, fully urbanized. Levittown was only the first of many new suburbs, and businesses followed residential development eastward.
Long Island is home to the Hauppauge Industrial Park, which was at one time, the East Coast's largest industrial park. The park has over 1,300 companies, and employs over 55,000 Long Islanders. Companies in the park and abroad are represented by the Hauppauge Industrial Association. It is noticeable to anyone visiting the park, that there is an abundance of For Rent or For Lease signs marking many of the properties. Many corporations that had long-term leases and moved out of facilities in the park, are still bound under lease-obligations. An example would be the news organization, Reuters Group, which occupies 3 separate facilities there, but shuttered its sites when it was acquired by the Thomson Corporation to become Thomson Reuters, in 2008. By sight alone, it appears that about 20-30% of the properties in the industrial park have been vacated.
A growing entertainment industry presence can also be found on the Island. Most recently producer Mitchell Kriegman established Wainscott Studios in Water Mill, where the PBS children's show It's a Big Big World is shot.
