The Beatles' history is intertwined with one pop-culture landmark after another.

The appearance of Paul McCartney, John Lennon, George Harrison and Ringo Starr on "The Ed Sullivan Show" in 1964 proved the power of then-fledgling rock 'n' roll. Their 1965 concert at Shea Stadium ushered in the era of stadium rock. And their quick-cut, effects-filled musical comedy "A Hard Day's Night" inspired a generation of music videos.

Will the release of "The Beatles: Rock Band" today provide another landmark - an event that will introduce a huge percentage of baby boomers to the video games they have been buying their children and grandchildren for years?

"If anything could, it's The Beatles," says Becky Ebenkamp, senior editor for Adweek Media. "Interest in them really is multigenerational."

Harmonix and MTV Games, makers of "The Beatles: Rock Band" and the entire Rock Band series, certainly are doing what they can to make it happen.

Two years in the making, the game was created with the input of McCartney, Starr, Yoko Ono and Olivia Harrison, and with Giles Martin, who co-produced The Beatles' "Love" project with his father, longtime Beatles' producer George Martin, handling the production of the music tracks for the game.

"The project is a fun idea which broadens the appeal of The Beatles and their music," McCartney said in a statement. "I like people having the opportunity to get to know the music from the inside out."

That idea isn't new, and it's certainly already popular, as the Guitar Hero series from Activision and the Rock Band series have shown for years. And for many teens and young adults, the allure of the game isn't the music, but the gameplay and the first-rate art direction and animations, not to mention the high-end peripherals that include replicas of McCartney's Hofner bass guitar, the Rickenbacker 325 guitar made famous by Lennon, Harrison's Gretsch Duo Jet guitar and a Starr-inspired Ludwig drum set complete with a replica Beatles kick drum head. Those stylish add-ons are a long way from the early plastic guitars with the multicolored buttons, though those will work with the game as well.

But for those who grew up with The Beatles' music, the idea of interacting with "I Want to Hold Your Hand" and "Here Comes the Sun" in a new way will be the prime selling point.

"It will be a way for families to bond over music," Ebenkamp says. "Kids can teach their parents how to play the game, and parents can teach their kids about the music. It will really work both ways."

The video game industry, which has been struggling this year as a result of the economic downturn, hopes "The Beatles: Rock Band" not only changes family dynamics, but purchasing patterns as well.

According to Anita Frazier, industry analyst for NPD Group, the industry is down 14 percent through July compared to the same period last year. The music-related video game segment, which includes everything from Rock Band to Dance Dance Revolution, has been hit the hardest, she said, with revenue down $390 million through July. However, "The Beatles: Rock Band" could help change that.

Frazier said video gamers older than 50 currently represent about 18 percent of spending on games this year, and targeting that age group could bring in new business.

"I think 'The Beatles: Rock Band' appeals to a broader audience than just those over 50," Frazier said. "While that may be the age range of original Beatles fans - or even 60s, right? - the band is a cultural icon, and even my kids, 12 and under, know a lot of

Beatles songs. But I do think there is continued effort on the part of the industry as a whole to recruit new audiences to play games in order to fuel industry expansion."

Time will tell how well "The Beatles: Rock Band" will hit its lofty artistic and economic targets among fans. However, for some involved with the game, it already is a success.

"(John Lennon) would have loved it," Yoko Ono told WENN Entertainment News. "'The Beatles: Rock Band' is about to create another revolution."
