An article on a webby:

"Billboard reports another week, another record-breaking jump to No. 1 on the Billboard Hot 100. Britney Spears makes a near-maximum 96-1 rise with “Womanizer,” returning to the top of the list for the first time since her debut single “…Baby One More Time” hit No. 1 in January 1999.

Spears’ single is spurred by first-week download sales of 286,000, the biggest opening-week tally by a female artist since Nielsen SoundScan began tracking digital downloads in 2003, besting Mariah Carey’s take for “Touch My Body” by just over 200 units.

In between her nearly 10-year gap between No. 1s, Spears has placed four other top 10s on the Hot 100, the last being “Gimme More,” the first single from her last set, “Blackout.” That song jumped 68-3 last October with first-week download sales of 179,000.

“Womanizer” previews Spears’ sixth studio set “Circus,” due Dec. 2 via Jive."

Can't imagine that I've been a Britney fan for almost 10 years!! Hopefully, Britney's comeback will be a huge blast this December with her 7th album! I'll be anticipating... (Anyway, Britney's latest single 'Womanizer' has since dropped to No. 4. Hope it'll be back at No.1 again :P)
