same quality berthing and most of the same facilities. (Passengers in cabins in certain grades on the Queen Elizabeth 2 had access only to certain dining rooms). Ocean liner services aimed at passengers ceased in 1986. The Rotterdam was put on permanent cruise service, as was the France, albeit modified and renamed Norway in 1980, as part of Norwegian Cruise Line. This made the Norway, by then the largest passenger vessel in the world, the first "mega-cruise ship". Cunard, on the other hand, put the Queen Elizabeth 2 on more cruises, but also, in an attempt to shift the focus of the market from passenger travel to cruising with entertainment value, pioneered the luxury transatlantic cruise service, catering to a niche market of those who appreciated the several days at sea. International celebrities were hired to perform acts onboard, along with cabarets, and with the addition of a casino and other entertainment amenities, the crossing was advertised as a vacation in itself. The 1970s television series Love Boat helped to popularize the concept as a romantic opportunity for couples. Another ship to make this transition was SS Norway, originally the ocean liner SS France and later converted to cruising duties as the Caribbean Sea's first "super-ship". Contemporary cruise ships built in the late 1980s and later, such as the which broke the size record held for decades by Norway, showed characteristics of size once reserved for ocean liners. The Sovereign-class ships were the first "megaships" to be built specifically for the mass cruising market. They also were the first series of cruise ships to include a multi-story lobby with a glass elevator and had a single deck devoted entirely to cabins with private balconies, instead of oceanview cabins. Other cruise lines soon launched ships with similar attributes, such as the , leading up to the Panamax-type , designed such that two-thirds of the oceanview staterooms have balconies. As the veranda suites were particularly lucrative for cruise lines, something which was lacking in older ocean liners, recent cruise ships have been designed to maximize such amenities and have been described as "balcony-laden floating condominiums". Until 1975–1980, cruises offered shuffleboard, deck chairs, "drinks with umbrellas and little else for a few hundred passengers". After 1980, they offered increasing amenities. As of 2010, city-sized ships have dozens of amenities. There have been nine or more new cruise ships added every year since 2001,
