Glenn Close, Anthony Hopkins, John Singleton, Ted Turner, Journey and 17-year-old twins Mary-Kate and Ashley Olsen will also get the sidewalk honor next year. The new inductees were announced Thursday by Johnny Grant, chairman of the Hollywood Chamber of Commerce.

"There's a favorite on this list for everybody. We have both young and veteran performers and local, national and international stars," Grant said. "The induction ceremonies will generate a lot of excitement for our residents and visitors from around the world."

The inductees represent film, television, radio, live theater and recording. Grant said they were chosen from hundreds of nominations during a June 13 meeting.

A caveat: Cannot be so sexy or with so much attitude that parents will protest. No drugs, not too much bare flesh and, ideally, the successful candidate will never grow up.

That is the delicate recruiting tightrope being walked by companies in search of young stars to market everything from cosmetics to clothes and cell phones to the increasingly powerful "tween" market.

These kids have greater influence over family buying decisions, more money of their own and a broader range of interests than previous generations. There are also more of them, because many are the grandchildren of baby boomers.

Some marketing estimates put their buying power in the United States alone at $300 billion a year -- a lot of money to miss out on if you get the tone of a campaign wrong or go with the wrong role model.

"The potential is huge for marketers and once they (tweens) obtain more money, it's only going to get bigger," said Cynthia Engelke of Youth Intelligence, a youth marketing research firm in New York City.

It's not that there isn't a wider choice of young stars than ever before, particularly among actresses and singers. For example, the cover of Vanity Fair's latest issue features nine female celebrities under the headline "It's Totally Raining Teens!" The magazine, which usually showcases more mature talent, gushes that, on the cultural and financial fronts, now more than ever, it is prime time for teen-agers.

BRITNEY SPEARS -- YESTERDAY'S STAR

But what worked last year may not work this year. A prime example of that is the fading appeal of pop star Britney Spears among tweens.

Spears quickly went from sassy songstress touting lucrative endorsement deals with Pepsi, AOL and Skechers footwear -- and earning $39.2 million in 2002, according to Forbes magazine -- to being seen as yesterday's star at the ripe old age of 21. Teenmag.com, the online version of Teen Magazine, said 54 percent of the 10- to 15 age group who responded to a poll in May, chose the description "so over" to describe Spears.

Some marketing experts say that Spears was overexposed and subsequently seen as pushing products rather than being creative. Contrary to popular myth, her overtly sexual image may also have contributed to her decline as a role model.

"Tweens began to realize that she's too commercial, not to mention too sexually charged," said Alicia Kolski, vice president of Amp Insights, the tween research arm of Alloy Marketing and Promotions. "Tweens are listening to artists for their talent or skill more so than for what they wear."

Parents still have a great influence over tweens and they can often be conservative. "We have them look through magazines and select what they think is for them and what's not," she said. "Things that are too sexy -- they tend to shy away from. They are just not comfortable."

Spears and young pop star Christina Aguilera also illustrate another problem. As teen-age stars grow up, they may start to appeal more to an adult market.

Among the most successful promoters to tweens are those who take the audience through their childhood. The most extreme example of that are the 17-year-old twins Mary-Kate and Ashley Olsen, who began their entertainment careers when they were babies. In the process, they have created a multimillion-dollar entertainment and consumer products empire, with estimates of their net worth at $300 million combined.

MOSTLY WHOLESOME OLSENS

The Olsens, who have maintained a mostly wholesome image, have their fingers in about 60 product categories, including a fashion and accessories line, a lifestyle magazine, movies, video games, a TV sitcom and fashion dolls.

"Everything was based on what they thought was appropriate," Michael Pagnotta, a spokesman for the Olsens' company Dualstar Entertainment Group said, recalling their decision to avoid shirts that exposed their navels.

Among the stars who might be bets to compete with the Olsens' dominance in the tween market is Hilary Duff, the 15-year-old star of the "Lizzie McGuire" movie and TV series.

Duff not only has the Olsens' natural image, but also her character displays the kind of angst that teens going through adolescence can identify with as real, Engelke said. Duff has her own line of products -- Stuff by Hilary Duff, set to hit stores next year, two movies, and the release in September of her debut CD "Metamorphosis."

Replacing her at the top is Jennifer Aniston, one of TV's "Friends" stars, who earned $35 million last year and appeared on more magazine covers than any other celebrity.

Jennifer "J-Lo" Lopez and Ben Affleck emerged as Hollywood's hottest new power couple, occupying the fifth and seventh spots on the list, with a combined income of $65 million.

It has not been a good year for Spears, who hit it big in 1999 with "Oops!..I Did it Again." She has had a string of bad press recently, as her much publicized relationship with Justin Timberlake of N'Sync went sour; her movie "Crossroads," was less than successful.

She was also photographed flipping off the paparazzi in Mexico after refusing to go on stage in a rain storm, while photos in the New York Post of her smoking also worked to tarnish her good-girl image.

"Good press or bad press, all press is equal in our eyes," said Peter Kafka, an editor at Forbes, the business magazine that compiled the list, which takes into consideration earnings, press clippings, radio and TV coverage and web hits.

"By dollar value, Britney did not have a big album or a big tour, the proponents that usually land celebrities on the list," said Kafka.

Rappers Eminem and Dr. Dre take the number 2 slot this year, also earning $35 million, but with nearly 2 million web hits. Golfer Tiger Woods slipped from 2 to 3, while earning $78 million -- $9 million more than last year.

Kafka said Aniston, whose husband, Brad Pitt, did not make the list, was a bit of a surprise. "Aniston's marriage may have helped to propel her to 13 covers, but she is still one of the highest paid actresses in Hollywood," he said.

Aniston's female "Friends," Lisa Kudrow (30) and Courteney Cox (41) made the list, but only one male co-star, Matthew Perry (25).

"Harry Potter" author J.K. Rowling, catapulted from 34 in 2002 to 15 this year amid anticipation about the latest book in the children's series. Rowling's earnings increased by about $90 million, up from $41.8 million.

While golfer Woods was by far the most powerful sports celebrity, basketball legend Michael Jordan was 13 with motor racing's Michael Schumacher at 19. Soccer star David Beckham entered the list at 56, but without Spice Girl wife Victoria.

Rounding out the top ten were movie director Steven Spielberg (4), ex-Beatle Paul McCartney (6), Oprah Winfrey (8), Tom Hanks (9) and The Rolling Stones (10).
