The Philadelphia 76ers tickets are in high demand this season, following the team’s 100th consecutive sellout game.

The 76ers, which just six years ago were at the bottom of the NBA’s attendance ranking, are now back on top. The team recently reported their 100th consecutive sellout game before beating the Miami Heat at the Wells Fargo Center last weekend. This sellout streak represents fans’ demand for Sixers tickets. According to CNBC, Sixers president Chris Heck said that the team only sold 3,500 season tickets during the 2013-2014 season, finishing 17th on ESPN’s NBA attendance ranking during that season and dropping down to 30th in 2015.

However, after advancing to the Eastern Conference semifinals, the team has seen a surge in tickets. Ticketmaster told CNBC that sales have spiked 91 percent through the first seven home games with average ticket prices rising 28 percent. The average ticket this season cost $131, up from the average of $95 in 2015. Heck explained that the increase in demand can be credited to Sixers CEO Scott O’Neil, who had decided to change their operation and rebuild the team’s “outdated” plan in 2014. He said the team had the chance to “wipe the dust off it and shine up.”

Over the past six years, Heck said the team listened to fans’ input during townhall meetings and allowed fans to move to better seats during games that weren’t sold out. They partnered with companies like Dunkin’ Donuts to advertise its logo and began to gain a stronger fan base along the way; they even gained a “cult following” of fans under the age of 35.

Following a season at No. 1 in attendance, the Sixers are yet again on top, averaging 20,508 fans at each game. The team has 14,000 season ticket holders and more than 10,000 fans on the waiting list.

The 76ers defeated the Pacers on Saturday and are set to take on the Utah Jazz tonight. This week, they’ll play the Wizards and Cavaliers, followed by games against the Raptors, Nuggets, Celtics, Pelicans, and Nets later this month.
