One of the many significant announcements today was Apple's announcement that they are partnering with America Online (AOL).
Through this partnership, Apple will gain access to AOL's 25 million U.S. subscribers. AOL will integrate iTunes links into their popular AOL Music site, providing direct links to the iTunes Music Store for both Mac and PC.
Early rumors that placed Apple and AOL together were apparently true. This partnership will allow AOL users to use Apple's iTunes Music store without even entering a credit card number. Users may simply use their AOL screenname to signon and purchase songs from the iTunes Music Store.
