Bloomberg reports that the search share of Microsoft's new search engine, Bing, rose to 11.1% in the first week of June. According to ComScore figures, this increase in the first week in operation was up from the 9.1% share in the US during the previous week. This is probably to be expected with the luanch publicity and advertising campaign as people try it out - no doubt promising news for Microsoft execs, but the real figures will need to be seen over a longer period of time to show that search habits can be changed.
