CBS Radio White House correspondent Mark Knoller, considered the unofficial historian of the press corps, has a must-read story giving a detailed review of President Obama's first year in office.

One number Knoller flags as "striking" is the number of interviews the president has done over the course of the year: 158 in total, including 90 televised Q-and-As. Knoller claims that this is "far more than any of his recent predecessors in their first year," and reflects a strategy of the White House that Obama "can best respond to questions in an interview setting." He also conducted 42 news conferences, compared to 21 in President Bush's first year.

Some other notable stats:

• Obama attended 28 fundraisers this year, far more than the six Bush held in his first year. But Bush raised more money at those events: $48 million, versus just under $28 million for Obama.
• 52 of his 411 official remarks this year focused on health care, or about one of every eight. All this for a legislative initiative that hangs in the balance after Scott Brown's shocking win in Massachusetts yesterday. The TelePrompter was used for 178 of those statements.
• He's traveled to 58 cities in 30 states, covering less ground than Bush (38 states) but more than President Clinton (22) in their first years.
