Facebook Mobile Ads Assessment Make For Troublesome New Details

NEW YORK (AP) — Facebook says the number of people logging in is continuing to grow more quickly than the number of ads delivered. This is in part because more people are using Facebook on mobile devices, where it shows a very small number of ads, Facebook said Wednesday. The finding implies that Facebook has room to grow in the still-nascent mobile advertising space. Facebook says it saw that trend in the first quarter, and that has continued in the current quarter. Facebook Inc., which is expected to begin trading publicly next week, added three paragraphs on mobile usage to regulatory filings. The changes came after executives met with prospective investors in New York and Boston ahead of its initial public offering of stock. The additions were likely in response to questions from investors. The Menlo Park, Calif.-based company is expected to price its IPO next Thursday and start trading on the Nasdaq Stock Market on Friday. It said last week that it expects its shares to price at $28 to $35 each, which could value the company at close to $100 bilion
