America Online will debut an improved audio/video search engine at Singingfish.com Wednesday, part of its strategy of building ad-supported standalone search destinations to attract non-AOL members. It's the first upgrade to Singingfish.com since AOL acquired the multimedia search player in late 2003. Other pieces of the AOL strategy include a recent investment in and partnership with travel search player Kayak, along with the launch of its own shopping search engine InStore. Other areas the company plans to explore include real estate and automotive, according to AOL's Brian Hoyt.
