since Snow White and the Seven Dwarfs. Disneyland opened on Sunday, July 17, 1955. Only Main Street and rides in some of the "lands" were completed, a total of 20 attractions. Entry to the park cost $1 and guests had to pay for each individual ride. They were ready for 11,000 guests but around 28,000 people arrived due to sales of counterfeit tickets. The opening was aired on ABC with actors Art Linkletter, Bob Cummings, and Ronald Reagan, who were all friends of Walt, hosting it. It garnered over 90 million viewers, becoming the most-watched live broadcast to that date. The opening was disastrous, and was dubbed as "Black Sunday" by the employees. Restaurants ran out of food, the Mark Twain Riverboat began to sink, several rides malfunctioned, and the drinking fountains were not working in the 100 °F. (38 °C) heat. Within its first week of being open, Disneyland had had 161,657 visitors, and by its first month the park had over 20,000 visitors each day. After its first year, 3.6 million people had visited the park, and after its second year, four million more guests came, making it more popular than the Grand Canyon and Yellowstone National Park. That year, the company earned a gross total of $24.5 million compared to the $11 million the previous year. Though Walt focused more of the park than on films, the company produced an average of five releases per year throughout the 1950s and 1960s. The animated feature films included Sleeping Beauty (1959), One Hundred and One Dalmatians (1961), and The Sword in the Stone (1963). Sleeping Beauty was a financial loss for the company, and at $6 million, it had the highest production costs for a film up to that point. One Hundred and One Dalmatians introduced animation technique using the xerography process to electromagnetically transfer the drawings to animation cels. In 1956, the Sherman brothers, Robert and Richard, were asked to produce a theme song for the television series Zorro. The company later hired them as exclusive staff songwriters, an arrangement that lasted 10 years. They wrote many of the songs for Disney's films and theme parks, and several of them were commercial hits. In the late 1950s, Disney ventured into comedy with the live-action films The Shaggy Dog (1959), which became the highest-grossing film in the U.S. and Canada for Disney at over $9 million, and The Absent
