The Eras Tour

The Eras Tour is Taylor Swift's sixth concert tour. It began on March 17, 2023 in Arizona and is currently still happening. The tour is for all of her albums.
Each concert lasts over three hours, and Taylor Swift sings 44 songs.
Background
Swift was going to do a tour called Lover Fest in 2020 for her album Lover but it got cancelled because of the COVID-19 pandemic.
On the week Swift released her album Midnights, her website in the United Kingdom said she was going to go on tour. On The Tonight Show Starring Jimmy Fallon on October 24, 2022, Swift said that she "should [go on tour]" and that "when it's time, [she will] do it". Then, 4 days later, on The Graham Norton Show, she said a tour would happen "soon-ish".
On November 1, 2022, Swift announced the Eras Tour on Good Morning America and she said it is "a journey through the musical eras of [her] career". She started the tour in the United States in 2023. At each concert, there are two opening acts and they change every few days.
Ticketmaster controversy
With the exception of two cities, the tickets for the concerts were sold only on Ticketmaster, which is owned by Live Nation Entertainment. Because a lot of people tried to buy tickets to the concert, the website had a lot of issues and it was very hard to get tickets. They said "the site was unprepared to accommodate the sheer force of hundreds of thousands of Swift fans" and that hundreds of thousands of tickets were sold. Some congresspeople, including Alexandria Ocasio-Cortez and Amy Klobuchar, said that Ticketmaster violated competition laws. The United States Department of Justice started investigating Ticketmaster.
