MusiCares and the 200+ music industry participants will promote this event with pledge cards mailed to databases of members, friends and associates. Individuals and companies will contribute to this event by making pledges on an hourly, daily or weekly basis or by corporate sponsorship. Mandi will promote this event by on-air local and network radio interviews and personal appearances on local and national network television prior to, during and following the Marathon. During her previous record-breaking events, she held local, national and international radio, television and print media interviews while playing at the pinball machine around-the-clock. In addition, she has been approached by a national late-night TV talk show to be a guest on the show during her world record attempt and immediately following completion of her 555th hour!

Marathon sponsors can link to the Marathon web site. In addition, footage will be shot for a documentary, tentatively titled "It Takes A Lot Of Balls," to be aired on network or cable TV.
