The alley behind the theater erupted into shrieks Wed- nesday night after band members stepped out of the stage door and walked to their cars. A crush of girls pressed up against the razor-wire fence; some lobbed roses and stuffed animals over the barrier. Then the screaming mob dashed into the street for one last glimpse as the police-escorted motorcade drove off.
A scene from "A Hard Day's Night"?
Nope. This is Jonas mania, not Beatlemania.
The Jonas Brothers are the youthful heartthrobs whose self-titled album has gone platinum. They are the latest beneficiaries of Walt Disney Co.'s tween-targeted star machine and could be the company's next creative franchise -- in the mold of "High School Musical" or "Hannah Montana."
Disney Radio and the Disney Channel helped propel the musical careers of the brothers Jonas -- Nick, 15, Joe, 18, and Kevin, 20 -- before the band was even signed in December 2006 by the parent company's label, Hollywood Records.
The exposure has turned the Jonas Brothers into a national media sensation. Last week, the brothers made appearances on ABC's "Dancing With the Stars," "Jimmy Kimmel Live," "The Ellen DeGeneres Show," Nickelodeon's Kids' Choice Awards and on a taping of "The Oprah Winfrey Show."
Now, Disney is throwing the full weight of its television group behind the Jonases' first movie, "Camp Rock." The TV movie will premiere June 20 on the Disney Channel and air over successive evenings on ABC, on cable channel ABC Family and online at Disney.com.
"This is a moment where the platforms of the television group combine to launch a potentially valuable new franchise, " said Anne Sweeney, president of Disney-ABC Television Group.
Television has long propelled the careers of cute, harmonic boy bands. The Fab Four crossed the Atlantic for their fateful Feb. 9, 1964, appearance on "The Ed Sullivan Show." The Osmonds got their start on "The Andy Williams Show."
The Disney Channel reincarnated "The Mickey Mouse Club" in 1989, launching the careers of Britney Spears, Christina Aguilera and half of 'N Sync: Justin Timberlake and J.C. Chasez.
Since the January 2001 debut of "Lizzie McGuire," the Disney Channel has become a powerful creative engine for its Burbank entertainment parent, producing a string of bankable names such as the Cheetah Girls, "High School Musical" and "Hannah Montana." The latter two are each expected to reap $1 billion in retail sales this year.
"They own the talent, they own the distribution, they can promote it all the time on television," said David Smay, co-editor of the book "Bubblegum Music Is the Naked Truth: The Dark History of Prepubescent Pop, From the Banana Splits to Britney Spears."
"It's almost impossible not to have a hit," he said.
Although Disney's tightly orchestrated media exposure of the Jonas Brothers is different from how boy bands were made in decades past, when such acts were the creations of independent music producers, the perils to young performers remain the same, Smay said.
"What usually happens is that they get ripped off, kind of dumped when they're no longer young and pretty. The Bay City Rollers' story was worse than Motley Crue," Smay said. "It's really difficult to survive that. Because there's so much money involved, people don't have the interest of the kids in front of them."
But the managers surrounding the group say the best protection for young artists is a solid family. In the case of the Jonas Brothers, they tour on a family bus that is limited to precisely that: family. Their father, Kevin Jonas, is a pastor who serves as the group's co-manager and grounding influence.
"We grew up with a rule: Even if at the top, look like you're at the bottom," Nick said. "It basically means to stay humble and keep the right attitude through the whole thing."
Like the Jackson 5, the Jonas Brothers are built around a musical prodigy -- in this case, Nick Jonas, who has performed on Broadway since he was 7, including a role as Chip in Disney's live production of "Beauty and the Beast." He signed with a major label at age 12 as a Christian pop artist.
Steve Greenberg unearthed Nick's eponymous CD in 2005, among a pile of recordings from artists Columbia Records wanted to drop. Greenberg, then the label's president, said Nick's voice stopped him cold and reminded him of a previous discovery: the pop/rock group Hanson, whose debut album sold 12 million copies globally.
"This was the best voice I've heard since Taylor Hanson," said Greenberg, now head of S-Curve Records, a New York music company. "You don't just let guys like this go."
Greenberg encouraged Nick and his brothers in their songwriting, making them CD mixes of '70s punk rock bands such as the Ramones for inspiration.
