More than 100,000 people signed up for health insurance through online exchanges last month.

"Bloomberg" cites an anonymous source, close to the federal healthcare program, who says the November numbers show a steady increase in online sign-ups since the program's troubled rollout on Oct. 1.

The majority of last month's sign-ups were through the exchanges run by 14 states and the District of Columbia, while roughly one-quarter were done through the federal marketplace.

The increase in November is good news for the Obama administration, which still expects most people to sign up next year as the March 31 deadline for buying health insurance approaches.
