(MONEY.CNN) — Arianna Huffington, who sold her news blog service The Huffington Post to AOL a year ago, will be assuming some additional responsibilities at the company.

Huffington will now have the technology, business development, marketing and communications operations that provide services for the Huffington unit at the company report directly to her, rather than having them report to other executives at AOL.

The shift is described by an official with the company as the formalization of the way things have been operating at the Huffington Post Media Group since the $315 million purchase of Huffington announced in February 2011. Huffington has served as president and editor and chief of that AOL unit since the purchase. She continues to report to AOL CEO Tim Armstrong.
