Paying attention to Yahoo!’s real-time search update? Here’s some relevant eMarketer data:

Yahoo!’s share of the $12.37 billion US search advertising market fell to 10.4% in 2010, down from 13.7% in 2009, according to eMarketer. This year, Yahoo!’s share of overall US search ad revenues is expected to fall further to 8.1%.

Much of the decline in Yahoo!’s search business is a result of Bing’s rise. eMarketer estimates Microsoft’s share of overall US search ad revenues increased to 10.2% last year — just shy of Yahoo!’s.
