NEW YORK, N.Y. -- After years of keeping quiet about his personal life, pop star Ricky Martin has announced that he is gay.

"I am proud to say that I am a fortunate homosexual man," Ricky said in a message posted on his offical Web site. "I am very blessed to be who I am."

Ricky Martin is Gay

Ricky said writing his memoir and thinking about his two twin sons led him to go public.

"To keep living as I did up until today would be to indirectly diminish the glow that my kids where [sic] born with. Enough is enough. This has to change. This was not supposed to happen 5 or 10 years ago, it is supposed to happen now. Today is my day, this is my time, and this is my moment," he wrote.

Though the 38-year-old kept his sexuality private throughout most of his career, Ricky said he drew strength from that time.

"These years in silence and reflection made me stronger and reminded me that acceptance has to come from within and that this kind of truth gives me the power to conquer emotions I didn't even know existed," he continued. "What will happen from now on? It doesn't matter. I can only focus on what's happening to me in this moment. The word "happiness" takes on a new meaning for me as of today. It has been a very intense process. Every word that I write in this letter is born out of love, acceptance, detachment and real contentment. Writing this is a solid step towards my inner peace and vital part of my evolution."

Earlier this month, Barbara Walters told The Toronto Star that her 2000 interview with the "Livin' La Vida Loca" singer, where she grilled him about coming out, was a misstep on her part.

"In 2000, I pushed Ricky Martin very hard to admit if he was gay or not, and the way he refused to do it made everyone decide that he was," she told The Toronto Star. "A lot of people say that destroyed his career, and when I think back on it now, I feel it was an inappropriate question."

Ricky also Tweeted a link to his coming out announcement on his Web site, simply writing, "my life."

In an earlier Tweet on Monday, the singer posted a quote attributed to the late Dr. Martin Luther King Jr.

"Our lives begin to end the day we become silent about things that matter. M.L.K.Jr.," he wrote.

The Electric Networked Vehicle concepts debuting today from General Motors are designed for use in high-population areas.

EN-V Xiao concept from General Motors

The city car of the future will seat two people, run on electric power and communicate with other vehicles to reach a destination faster while automatically avoiding traffic tie-ups and crashes. General Motors, working with electric-scooter maker Segway, has developed three concepts tailored toward that vision of future transportation. The Electric Networked Vehicle, or EN-V, concepts go on display May 1 at the World Expo in Shanghai.

The EN-V concepts are a next-generation vehicle from the Personal Urban Mobility and Accessibility prototype that GM debuted at the New York auto show a year ago.

There are three concepts, one each from GM's design studios in Australia, Europe and the United States.

The concept from Holden in Australia is named Xiao, or Laugh, and is painted blue. The U.S. concept, Miao, or Magic, is dark silver and used light-emitting diode accent lighting. The Europe concept, Jiao, or Pride, is red. Its design is influenced by bullet trains.

The pod-looking vehicles measure about 60 inches long, 56 inches wide and range from 65 inches to 69 inches tall. The weight averages 900 pounds, with half of that concentrated in the chassis platform. The bodies are built from lightweight plastic and carbon fiber.

GM says an EN-V is about one-third the length of a traditional car. A parking lot could hold 10 times the number of EN-Vs as regular cars.

All of the EN-V concepts are powered by a Segway powertrain--brushless direct-current wheel motors that provide propulsion and braking. GM says the EN-V can reach a top speed of 25 mph and travel 25 miles on a full charge of its lithium-ion battery pack. The battery is recharged by plugging in to standard household current.

A key to making all these EN-Vs work in dense urban environments is an array of sensors and wireless communication. GM says the EN-V is constantly talking with traffic-management networks and control signals to automatically find the most efficient route to the destination. Sensing technologies--such as GPS, lane departure and radar distance control used in today's vehicles--let the EN-V platoon, or travel in tight groups to maximize road capacity without crashing. Sensors would detect if a pedestrian steps in the way and automatically brake the EN-V to a stop.

3D TVs are starting to arrive in stores, and consumers have a lot of questions. The big one, of course, is whether these new TVs can recreate the 3D excitement we've been getting in movie theaters in our own homes. Based on our exclusive tests of the first models available, the answer is a resounding "yes."

Here are seven things you need to know about 3D:

1. It looks great.

The results of our preliminary tests of two Samsung LCD sets and a Panasonic plasma TV have been impressive. The high-definition, 1080p images on these TVs have excellent three-dimensional depth, color, and detail — especially with animated content-creating a compelling and realistic three-dimensional experience. You'll be ducking when that Frisbee comes flying toward you!

2. A few sets are in stores now, with more to come soon.

As of mid-March, there are three 3D TVs in stores: two LCD sets from Samsung, the 46-inch UN46C7000, $2,600 at Sears, and the 55-inch UN55C7000, $2,970 at Best Buy and $3,300 at Sears. The 50-inch Panasonic TC-P50VT20 plasma we tested is available in select Best Buy Magnolia stores for $2,500. 3D TVs from other brands (including LG, Sony, Toshiba, and Vizio) are expected to arrive over the next few months.

3. You have to wear special glasses to watch 3D on a TV.

Without glasses, you'll see blurry double images. These aren't the old-fashioned cardboard glasses you used to get at movie theaters, but high-tech active LCD shutter glasses. You can put them over your regular specs, though some might find this uncomfortable. You get one or two pairs of glasses with some 3D TVs, but other sets don't include any. Expect to pay about $150 for each pair of glasses, at least initially.

4. A 3D set isn't just for 3D.

It functions like any standard TV with regular programs, and shifts into 3D mode when it detects 3D content. You don't have to wear glasses to watch regular programming.

5. The only thing to watch in 3D right now are movies on Blu-ray discs.

3D TV channels from DirecTV, ESPN are expected this summer, and the Discovery Channel is expected to offer 3D at some point soon, but for now, movies are the only game in town. Monsters vs. Aliens is one of the first 3D movies available, but more are coming soon, including Ice Age: Dawn of the Dinosaurs, expected in April. You'll need to buy a new 3D-capable Blu-ray player (about $400) to play these discs. (There are some older 3D movies — such as Journey to the Center of the Earth, Polar Express, and Coraline — that use the old-style cardboard anaglyph glasses, but they're not comparable to the new 3D.)

6. Prices aren't sky-high.

The 3D TVs announced so far cost several hundred dollars more than regular sets that have similar features (aside from 3D). The lowest-priced 3D set now on the market, a 50-inch Panasonic plasma, costs $2,500. Lower-priced models are due soon, including a 46-inch $1,700 LCD set and an $1,800 50-inch plasma TV from Samsung.

7. Buying now makes sense for some consumers.

If you're in the market for a fairly high-end TV anyway, you might want to consider a 3D set. It won't cost much more than a regular TV, and you won't have to think about buying yet another new TV in a year or two when there's lots of 3D content to watch, both on TV and on Blu-ray discs. There are only a few sets on the market now, but you'll have more of a selection in a few months. However, if you don't need a new TV, we wouldn't rush out to buy one (unless you're a well-heeled early adopter itching for the latest and greatest technology). Prices for 3D TVs and Blu-ray players are no doubt going to drop over time, you'll have more models to choose from, and there'll be more 3D to watch. Catch up with our ongoing coverage of 3D TV in our earlier posts.

The Jimi Hendrix Experience's Valleys Of Neptune enters The Billboard 200 at #4, putting the rock legend back in the top five nearly 40 years after he died at the tragically young age of 27. No other artist has cracked the top five this long after his death. Elvis Presley is in second place. His Elvis: 2nd To None debuted at #3 in October 2003, a little more than 26 years after his death.



Hendrix is the second music legend to make the top five posthumously in the past two weeks. Johnny Cash bowed at #3 two weeks ago with American VI: Ain't No Grave. But Cash died less than seven years ago. It's more remarkable for an artist who died four decades ago to make significant chart waves.

Valleys Of Neptune is, incredibly, Hendrix's 34th posthumous album to make The Billboard 200.

Hendrix was a star for just three years, from June 1967, when he played the Monterey International Pop Festival, to September 1970, when he died in London of a drug overdose. The guitar hero had four top five albums in his lifetime. This is his third top five album since his death. It follows The Cry Of Love, which hit #3 in 1971, and Crash Landing, which reached #5 in 1975.

Four of Hendrix's catalog albums re-enter The Billboard 200 this week. 1967's Are You Experienced? bows at #44, followed by 1968's Electric Ladyland at #60, the 1997 compilation First Rays Of The New Rising Sun at #63 and 1968's Axis: Bold As Love at #67.

Experienced? first cracked The Billboard 200 on Aug. 26, 1967. It was only the 10th highest new entry of the week (!), opening at an unimpressive #190. The album took 59 weeks to reach its #5 peak in October 1968. This week's debut of Valleys Of Neptune gives Hendrix a nearly 41-1/2 year span of top five albums.

Carlos Slim Helu takes No. 1 spot on Forbes World's Billionaires list as a record 164 10-figure titans return to the ranking amid the global economic recovery.

For the third time in three years, the world has a new richest man.

Riding surging prices of his various telecom holdings, including giant mobile outfit America Movil (AMX), Mexican tycoon Carlos Slim Helu has beaten out Americans Bill Gates and Warren Buffett to become the wealthiest person on earth and nab the top spot on the 2010 Forbes list of the World's Billionaires.

Slim's fortune has swelled to an estimated $53.5 billion, up $18.5 billion in 12 months. Shares of America Movil, of which Slim owns a $23 billion stake, were up 35% in a year.

That massive hoard of scratch puts him ahead of Microsoft (MSFT) cofounder Bill Gates, who had held the title of world's richest 14 of the past 15 years.

Gates, now worth $53 billion, is ranked second in the world. He is up $13 billion from a year ago as shares of Microsoft rose 50% in 12 months. Gates' holdings in his personal investment vehicle Cascade (CAE) also soared with the rest of the markets.

Buffett's fortune jumped $10 billion to $47 billion on rising shares of Berkshire Hathaway (BRK). He ranks third.

The Oracle of Omaha shrewdly invested $5 billion in Goldman Sachs (GS) and $3 billion in General Electric (GE) amid the 2008 market collapse. He also recently acquired railroad giant Burlington Northern Santa Fe (BNI) for $26 billion.

In his annual shareholder letter Buffett wrote, "We've put a lot of money to work during the chaos of the last two years. When it's raining gold, reach for a bucket, not a thimble."

Many plutocrats did just that. Indeed, last year's wealth wasteland has become a billionaire bonanza. Most of the richest people on the planet have seen their fortunes soar in the past year.

This year the World's Billionaires have an average net worth of $3.5 billion, up $500 million in 12 months. The world has 1,011 10-figure titans, up from 793 a year ago but still shy of the record 1,125 in 2008. Of those billionaires on last year's list, only 12% saw their fortunes decline.

U.S. billionaires still dominate the ranks — but their grip is slipping. Americans account for 40% of the world's billionaires, down from 45% a year ago.

The U.S. commands 38% of the collective $3.6 trillion net worth of the world's richest, down from 44% a year ago.

Of the 97 new members of the list, only 16% are from the U.S. By contrast, Asia made big gains. The region added 104 moguls and now has just 14 fewer than Europe, thanks to several large public offerings and swelling stock markets.

The new billionaires include American Isaac Perlmutter, who flipped Marvel Entertainment (MVL) to Disney (DIS) for $4 billion last December. The Spider-Man mogul netted nearly $900 million in cash and 20 million shares of Disney in the transaction.

Also new to the ranking: 27 billionaires from China, including Li Shufu, whose automaker, Geely, announced plans to buy Swedish brand Volvo from Ford in December. The deal is expected to close in March 2010.

Finland and Pakistan both welcomed their first billionaires.

For the first time China (including Hong Kong) has the most billionaires outside the U.S. with 89.

Russia has 62 billionaires, 28 of them returnees who had fallen off last year's list amid a meltdown in commodities. Total returnees to the list this year: 164.

Eleven countries have at least double the number of billionaires they had a year ago, including China, India, Turkey and South Korea.

Thirty members of last year's list fell out of the billionaire's club. Moguls who couldn't make the cut: Iceland's Thor Bjorgolfsson, Russia's Boris Berezovsky and Saudi Arabia's Maan Al-Sanea.

Another 13 members of last year's list died. Among the deceased: real estate developer Melvin Simon and glass tycoon William Davidson.
