In the 9th century, the per capita income in Europe increased by 2 times and that in the United States by 3 times, which was unprecedented in human history before the industrial revolution. The rapid increase of residents' income level made people have the ability to pay for traveling abroad. By 1875, the annual passenger turnover in Britain had exceeded 611 million people/mile. 2. Rapid transportation has facilitated the development of tourism activities. From the completion of the world's first railway in 1825 to 1865, the total length of British railways has reached more than 21,111 kilometers. By 1851, 15 countries in the world had built railways and carried out passenger and cargo operations. In terms of water transportation, steamships across the English Channel officially started shipping in 1821, and since 1838, Britain has opened regular flights across the Atlantic Ocean and the Pacific Ocean, which not only created good conditions for people to travel in Britain, but also facilitated tourism activities between Europe and the United States. 3. Perfection of tourism service institutions and facilities, improvement of service quality and improvement of comfort. First of all, in terms of tourism service institutions, since the first travel agency was established in Thomas Cook in 1865, Europe, North America and Japan have successively established tourism institutions. The development of tourism business from one-day tour to multi-day package tour, from domestic tour to foreign tour, the issuance of various travel newspapers, train tickets, travel accommodation vouchers and traveler's checks not only expanded the scale and business scope of tourism, but also laid the foundation for tourism to become a world-wide industry. Secondly, in the accommodation industry and catering industry; Hotels have replaced hotels, and many hotels have appeared along the traffic lines in Britain, as well as in major cities, and catering facilities and services have been greatly improved. Since 1774, the new york City Hotel with indoor toilets, private dining rooms, banquet halls, dance halls, billiard rooms and other facilities was built in Boston, USA, with 311 rooms. By 1912, more than 1,511 hotels with more than 51 rooms had been built in the United States, and many large hotels were also built near railway stations in Britain. Finally, in the entertainment industry, with the increase of tourism demand, not only some hotels have entertainment facilities, such as dance halls and billiard rooms, but also the construction of seaside resorts has begun.
