Question: As of 2014, how long had the city served by WAJM held a monopoly on casino gambling?

full_context: Document 1: Atlantic City, New Jersey: Owing to economic conditions and the late 2000s recession, many of the proposed mega casinos never went further than the initial planning stages. One of these developers was Pinnacle Entertainment, who purchased the Sands Atlantic City, only to close it permanently November 11, 2006. The following year, the resort was demolished in a dramatic, Las Vegas styled implosion, the first of its kind in Atlantic City. While Pinnacle Entertainment intended to replace it with a $1.5–2 billion casino resort, the company canceled its construction plans and plans to sell the land. The biggest disappointment was when MGM Resorts International announced that it would pull out of all development for Atlantic City, effectively ending their plans for the MGM Grand Atlantic City.
Document 2: Atlantic City, New Jersey: With the redevelopment of Las Vegas and the opening of two casinos in Connecticut in the early 1990s, along with newly built casinos in the nearby Philadelphia metro area in the 2000s, Atlantic City's tourism began to decline due to its failure to diversify away from gaming. Determined to expand, in 1999 the Atlantic City Redevelopment Authority partnered with Las Vegas casino mogul Steve Wynn to develop a new roadway to a barren section of the city near the Marina. Nicknamed "The Tunnel Project", Steve Wynn planned the proposed 'Mirage Atlantic City' around the idea that he would connect the $330 million tunnel stretching 2.5 miles (4.0 km) from the Atlantic City Expressway to his new resort. The roadway was later officially named the Atlantic City-Brigantine Connector, and funnels incoming traffic off of the expressway into the city's marina district and Brigantine, New Jersey.
Document 3: Atlantic City, New Jersey: In the wake of the closures and declining revenue from casinos, Governor Christie said in September 2014 that the state would consider a 2015 referendum to end the 40-year-old monopoly that Atlantic City holds on casino gambling and allowing gambling in other municipalities. With casino revenue declining from $5.2 billion in 2006 to $2.9 billion in 2013, the state saw a drop in money from its 8% tax on those earnings, which is used to fund programs for senior citizens and the disabled.
Document 4: Atlantic City, New Jersey: In an effort at revitalizing the city, New Jersey voters in 1976 passed a referendum, approving casino gambling for Atlantic City; this came after a 1974 referendum on legalized gambling failed to pass. Immediately after the legislation passed, the owners of the Chalfonte-Haddon Hall Hotel began converting it into the Resorts International. It was the first legal casino in the eastern United States when it opened on May 26, 1978. Other casinos were soon constructed along the Boardwalk and, later, in the marina district for a total of eleven today. The introduction of gambling did not, however, quickly eliminate many of the urban problems that plagued Atlantic City. Many people have suggested that it only served to exacerbate those problems, as attested to by the stark contrast between tourism intensive areas and the adjacent impoverished working-class neighborhoods. In addition, Atlantic City has been less popular than Las Vegas, as a gambling city in the United States. Donald Trump helped bring big name boxing bouts to the city to attract customers to his casinos. The boxer Mike Tyson had most of his fights in Atlantic City in the 1980s, which helped Atlantic City achieve nationwide attention as a gambling resort. Numerous highrise condominiums were built for use as permanent residences or second homes. By end of the decade it was one of the most popular tourist destinations in the United States.
