NetJets Inc., a subsidiary of Berkshire Hathaway, is an American company that sells part ownership or shares (called fractional ownership) of private business jets. NetJets was founded in 1964 as Executive Jet Aviation. It was the first private business jet charter and aircraft management company in the world.
By March 2018, Netjets had over 7,000 owners, operates more than 300,000 flights per year between 3,200 airports in 150 countries and flew 150,000,000 mi (240,000,000 km) in the previous year.
NetJets Inc., formerly Executive Jet Aviation, was founded in 1964 as the first private business jet charter and aircraft management company in the world. The founding members of the board of directors included Air Force generals Curtis E. LeMay and Paul Tibbets Jr., Washington lawyer and former military pilot Bruce Sundlun, and entertainers and pilots James Stewart and Arthur Godfrey, with retired Air Force Brigadier General Olbert F. "Dick" Lassiter serving as president and chairman of the board. EJA initially began operations in 1964 with a fleet of ten Learjet 23 aircraft. Bruce Sundlun became EJA president in 1970 and Paul Tibbets became president in 1976. By the late 1970s, EJA was doing business with approximately 250 contract customers and logging more than three million miles per year.
In 1984, Executive Jet Aviation was purchased by mathematician and former Goldman Sachs executive Richard Santulli who owned a business that leased helicopters to service providers of offshore oil operations. When Santulli became chairman and CEO of the corporation, he closely examined 22 years of pilot logbooks and began to envision a new economic model where several individuals could own one aircraft.
In 1987, the NetJets program was officially announced becoming the first fractional aircraft ownership format in history. Around the same time, painted on every NetJets US aircraft was a three-digit tail number punctuated with QS, symbolizing the revolutionary concept of selling Quarter Shares of an aircraft—a feature that is still representative of the NetJets brand today.
NetJets soon expanded to Europe and then Russia, and by 2006 was the largest supplier of business jets in Europe and the ninth largest air carrier overall on the continent.
In early August 2009 Santulli resigned as CEO and was replaced by David Sokol. NetJets Inc. has moved its corporate headquarters from New Jersey back to its original home in Columbus, Ohio, following the departure of the company's founder, Richard Santulli.
In 2010, NetJets acquired Marquis Jet from founders Jesse Itzler and Kenny Dichter. The prepaid Marquis Jet card allowed customers to purchase 25 hours of guaranteed flight time on the NetJets fleet.
NetJets sells fractions of specific aircraft, chosen from several available types at the time of purchase. Owners then have guaranteed access (50–400 hours annually, depending on share size) to that aircraft with as little as four hours notice. If the owner's aircraft is unavailable for some reason, another aircraft of the same type, or a larger aircraft, will be provided. Fractional owners pay a monthly maintenance fee and an "occupied" hourly operating fee. The latter is charged only when an owner or guest is on board, not when the aircraft is flying to a pick up point, or flying to another location after completing a flight.
For companies or individuals that require less than the minimum 50 flight hours and the five-year commitment of fractional ownership, they can buy flight hours in 25-hour increments via its Marquis Jet and NetJets jet card programs. 
The Internal Revenue Service (IRS) sought back taxes and penalties of $643 million from NetJets for periods beginning in 2003. NetJets filed a lawsuit challenging the IRS assessments. In January 2015, the United States District Court issued a decision in NetJets’ favor, holding that the IRS assessments were unlawful.
