Microsoft Corp.'s (MSFT) new Bing search engine continued to gain market share in its second week of availability, said data tracker comScore Inc. (SCOR).

The software giant, long an also-ran to Google Inc. (GOOG) in the search space, is hoping Bing creates a beachhead to have Microsoft become a bigger player in the online-advertising arena. A $100 million marketing campaign is supporting Bing's launch.

The service saw its market share of number of searches rise to 16.7% last week from 15.8% a week earlier, said comScore. The figure was 13.7% in the last week of May.

Microsoft's share of search results pages, a measure of the intensity of search activity by online users, climbed to 12.1% from 11.3% and 9.1%, respectively.

ComScore senior vice president Mike Hurt said the data "reflect a continued positive market reaction to Bing in the initial stages of its launch."

Google's market share has hovered around 60%, while Yahoo Inc. (YHOO) is next at about 20%.
