Oct 20 (Reuters) - Global events company MARI said on

Monday it has acquired TodayTix Group (TTG), getting access to

its platforms that sell tickets for live performances ranging

from operas in New York to plays by London's Royal Shakespeare

Company.

The deal adds to MARI's rapidly expanding portfolio

since its launch just earlier this month by Ari Emanuel - a

Hollywood power broker who is also the CEO of TKO Group ( TKO ),

the owner of Ultimate Fighting Championship and World Wrestling

Entertainment.

He is also the executive chairman of WME Group, a

holding company of talent agencies.

MARI has already acquired the Miami Open tennis

tournament, Frieze art fairs, and Barrett-Jackson auto auctions.

MARI acquired TTG from private equity firm Great Hill

Partners. Financial terms of the deal were not disclosed.

TTG, which also owns London's immersive film and

television producer Secret Cinema, operates in the U.S., UK and

Australia, has over 20 million members and partners with more

than 10,000 cultural institutions. Its brands also include

LondonTheatre and Show-Score.

Brian Fenty, TodayTix's co-founder and CEO, will continue

leading the company and join MARI's executive team, while

co-founder Merritt Baer will remain Artistic Director for Secret

Cinema.
