Looks like the merger is on schedule.
Organic Search Results. Last week (August 17) Bing announced that they would begin powering organic search results on Yahoo! Search for the English language in the United States and Canada within days. After this organic transition is complete, Bing will power 5.2 billion monthly searches, which is 31.6 percent of the search market share in the United States and 8.6 percent share in Canada.
Paid search. Earlier it was announced that the merger of the Yahoo Search Marketing & Microsoft/Bing AdCenter platforms would be completed in September or October. It looks like this is on track too as there are reports around the world of some Bing PPC ads appearing on Yahoo.
