New Yorkâ€”Business 2.0 could soon be shuttered. The monthly publication, which was founded in 2000 and is now part of Time Inc.â€™s Business and Finance Network, continues to struggle adwise. Ad revenue in the first half fell 30.1% compared with the same period in 2006, according to the Publishers Information Bureau. Ad pages declined 34.1% during the same period, according to PIB. A report last week in the New York Times said the San Francisco-based magazine might publish its final issue in September. However, a person familiar with the situation told BtoB the plug will be pulled Aug. 1. This person added that Time Inc. is blocking efforts to buy the magazine because it doesnâ€™t want it as a competitor. Time Inc.â€™s Business and Finance Network also includes Fortune, Fortune Small Business and CNNMoney.com.
