MediaBay has teamed up with OverDrive to offer e-books through its Web site, which currently features downloadable audio. The program launched with more than 1,000 titles available through the site, and MediaBay will add more titles as demand grows. The titles are available in both the Microsoft Reader and Adobe Acrobat eBook Reader formats and are from such publishers as McGraw-Hill, Time Warner Trade Publishing and Taylor & Francis. Although demand for downloadable audio has been weaker than expected, MediaBay CEO Michael Herrick predicted, "Over time, we expect that e-books will represent a meaningful source of revenue and profits."
