MTV has signed on reality veteran The Real World for four more seasons.

According to The Hollywood Reporter, the order will extend the 17-year-old docudrama from Bunim-Murray Prods. to an incredible 26 cycles. MTV also is ordering another four rounds of Bunim-Murray's The Real World/Road Rules Challenge, bringing the competition series to 21 cycles.

The deal was brokered by Gil Goldschein, who has been promoted to president of Bunim-Murray. The current season of "The Real World: Brooklyn" will air its finale Wednesday, and producers are shooting the next round, "The Real World: Cancun."

Given MTV's youthful target audience, the network must develop a constant stream of new, hip programming. But the "Real World" format keeps managing to hook new generations of viewers.

"MTV is proud to continue our relationship with Bunim-Murray that stretches back over 15 years," MTV programming president Tony DiSanto said. "With each new season, the 'Real World' franchise continues to evolve and captivate our ever-changing audience."

Producers tweaked the format for the Brooklyn season by not giving the cast members jobs.

"It's something I've been wanting to do for a while, and it's easier to do in a big metropolitan area," Murray said. "The season after Cancun, a location that hasn't been announced yet, I think might be like that too."
