While searching Yahoo News for the term "money market" (in quotes), we noticed a new paid advertising link to the new AARP Money Market Fund, which is currently yielding 5.07%. (Crane Data, which also advertises via web search keywords, doesn't list the fund yet because it is too small. We also have yet to receive performance data from the fund.) AARP MMF joins Fidelity Investments, the only other money market fund buying the "money market" keyword, and a number of banks and brokerages, in testing web search ad words on Yahoo.
