New Yorkâ€”Adweek, part of Nielsen Business Media's Adweek Group, plans to reduce its print frequency from 47 issues a year to 36, while boosting its Web presence. The reduction in frequency will go into effect in the first quarter. Sabrina Crow, senior VP-media and marketing group at Nielsen Business Media, said in a statement: "While our magazine continues to be an essential element of this iconic, multiplatform brand, we are moving with our audience by relaunching Adweek.com to maximize the value we provide our community." No details were released regarding the planned Web site enhancements. The announcement of the changes came less than a week after Greg Farrar was officially named CEO of Nielsen Business Media. He had been acting CEO since the sudden death of Bob Krakoff in March. The Adweek Group also includes Brandweek and Mediaweek.
