Washington, Jan. 31 : It took four years for Google to address the "Google bomb" that was lobbed at former President Bush, but just a few days to defuse the same attack on President Obama.

Four years versus a few days ... Some Googlers are asking why.

In 2003, President Bush''s detractors successfully gamed the Google search engine by arranging to have countless Web sites link the words "miserable failure" to Bush''s official biography on the White House Web site.

The result was that when someone typed the search term "miserable failure" into the Google search box, Bush''s biography rose to the top of the search results.

And, according to Fox News, that''s how it stayed until 2007, when Google developed an algorithm to detect what became known as "Google bombs" and re-directed the term "miserable failure" to non-political pages.

Unfortunately for Obama, "miserable failure" reverted back to his biography when he moved into the White House. The new president was also Google-bombed with the phrase "cheerful achievement."

But this time, Google stepped in quickly, rectifying the situation in a few days, instead of four years.

The difference in time did not go unnoticed.

"You let this go on for the entire Bush administration," a reader named w3bgrrl wrote on a Google blog. "But since you bought the White House for Obama, you don''t want your candidates harmed ... And your claims not withstanding, even liberals know you''re liberal."

But another writer, Mikkel deMib Svendsen, gave Google the benefit of the doubt.

"I do think many of [Google employees] are liberals but I am also 100% confident that the large majority of them are also very professional people that take the job of creating a good and unbiased search engine very, very seriously," he wrote.(ANI)
