Already king of venue ticket sales, Ticketmaster announced late Tuesday it was buying music festival ticketing service Front Gate Tickets of Austin and Toronto do-it-yourself ticketing website Universe. Terms of the deals were not disclosed.

Music festivals and events organized online are fast-growing, highly profitable markets that Ticketmaster covets.

Buying Front Gate Tickets, a company that processed more than $300 million in sales in 2014, will give Ticketmaster a bigger slice of the music festival ticketing market. Front Gate services music festivals such as Coachella, Austin City Limits and Lollapalooza.

Ironically, the grand-daddy of all music festivals, the Coachella Music Festival of Indio, got its start, in part, as a reaction to Ticketmaster’s dominance of venue ticket sales.

The Empire Polo Club of Indio, where Coachella takes place each year, became a popular music venue after Pearl Jam played a concert there in 1993 to boycott Ticketmaster’s high fees. The music festival market since has grown rapidly, often without ticketing services from Ticketmaster.

Ticketmaster has nevertheless been muscling its way into the music festival scene, buying up event promoter C3 Presents of Austin, the popular Bonnaroo Music and Arts Festival of Manchester, Tenn., and now Front Gate Tickets.

Apparently loathe to be on the outside again, Ticketmaster’s acquisition of Universe will bolster the company’s dive into another fast-growing ticketing market: do-it-yourself online ticketing sales.

Similar companies, such as Eventbrite of San Francisco, which has a valuation of over $1 billion, have found a lucrative niche facilitating ticketing for events such as professional networking get-togethers, hobbyist meet ups and other types of entertainment events.

Ticketmaster bought ticketing company eventjoy of San Francisco in 2014, and Universe will give the company a roster of more than 28,000 independent organizers and will help it keep pace with the next big thing.
