has become commonplace practice for event ticket sale opportunities used among the leisure and entertainment industries alike for concerts, theater, and sporting events. Grad Night In response to a high school night the preceding year, in which students were involved in a tragic automobile accident, Jack Lindquist and co-worker, Bill Schwenn, met with several women from local high school Parent-Teacher Association(PTA) groups to discuss the opportunity for a safe graduate evening party within the Disneyland park. Realizing that it would not be operationally feasible to justify opening the park only for the total of 800 students the women represented, Lindquist opened the event to additional area high school graduating classes. To fill the park so that it could afford to adequately staff and run the park for the Grad Night evening, tickets were sold to students from eight Southern California high schools, at a cost of $3.95 per ticket, from which a total of 8,500 attended on the first Grad Night party of June 15, 1961. As a result of the success of this first event, Disneyland's Grad Night became an annual event. By 2012, Disneyland had hosted over five million graduates from thousands of Southern California high schools. In 2013, the Grad Night event moved out of the Disneyland park and into the adjacent Disney California Adventure park. The tradition of Grad Night proved so successful that it continued every year since 1961 in Anaheim, and eventually grew to also take place at the parks in Walt Disney World, Tokyo Disneyland and Disneyland Paris. Aside from the annual Grad Night at the Disney parks, many industry parks plan similar annual special events for graduating high school seniors. Knott's Berry Farm in Buena Park, CA, the Six Flags theme parks, Universal Studios theme parks and even Dollywood in Pigeon Forge, Tennessee, all promote an annual special event to open the park to graduating high school seniors in the evening hours. Anniversary tie-ins and giveaways A popular marketing campaign that Jack Lindquist also pioneered, which is now repeated industry-wide among parks, started with the anniversary tie-in. In a desire to capture some of the millions of visitors attending the 1984 Olympics that were to take place in Los Angeles, Lindquist realized that the year would also be the 30th anniversary of the Disneyland park. While 30th anniversaries are rarely a cause for celebration, it would be marketed, regardless, as a milestone
