NEW YORK (

TheStreet

) -- Popular searches on the Internet Monday include

Warren Buffett

as the billionaire investor and CEO of

Berkshire Hathaway

said he would be buying single-family homes right now.

Buffett said on

CNBC

that single-family homes are currently an attractive investment, and an even better choice than stocks if purchased at low rates and held for a long time. He told buyers to take out a 30-year mortgage and refinance if rates go down.

Buffett is also a hot topic after his letter Saturday to shareholders, which included an announcement that Berkshire's board knows who will succeed Buffett as CEO if and when he is unable to continue in his position. While Buffett revealed that the successor doesn't know that he or she has been chosen and that the person isn't a member of the board, he wouldn't indicate who his successor will be.

Elpida

is another popular search as the Japanese computer memory chipmaker filed for bankruptcy on declining prices for DRAM chips.

The company is the only Japanese manufacturer to specialize in DRAM chips, and said its business was impacted when prices of the chips began to slide in 2007. The global economic downturn, as well as competition, flooding in Thailand last year and the climbing yen all weighed on the company.

Elpida reported debt of 448 billion yen ($5.5 billion) in the filing, which is Japan's largest manufacturing bankruptcy.

A hot topic Monday also is the Oscars, following the 84th Academy Awards on Sunday night.

Black and white silent film

The Artist

was the big winner of the night, taking home five awards, including best picture, director and lead actor for Jean Dujardin. Martin Scorsese's

Hugo

won five awards as well. Meryl Streep won best actress for her portrayal of British Prime Minister Margaret Thatcher in

The Iron Lady

. Streep has been nominated for an Oscar 17 times, more than any other performer, but has only won three -- with her last award being for

Sophie's Choice

in 1983.

Christopher Plummer, 82 years old, became the oldest person to win an acting Oscar for his supporting role in

Beginners

, while Octavia Spencer won best supporting actress for her role in

The Help

.
