Limited partnerships: general partner who organizes and sells a limited partnership. Sponsors (also called promoters) rely on their reputation in past real estate, oil and gas, or other deals to attract limited partners to their new deals.
Mutual funds: investment company that offers shares in its funds. Also called the underwriter.
Stocks: important investor-typically, an institution, mutual fund, or other big trader-whose favorable opinion of a particular security influences other investors and creates additional demand for the security. Institutional investors often want to make sure a stock has wide sponsorship before they invest in it, since this should ensure that the stock will not fall dramatically.

1. advertiser who pays for part or all of a television or radio program by running one or more advertisements during the program. Sponsorship entitles the advertiser to a mention as the program's sponsor, and to a specific amount of commercial time throughout the program, depending on the time of day, the type of program (local vs. network), and the station's regulations.
2. donor who provides a substantial portion of the funding to an event. Event sponsors typically receive publicity such as banners and signs at the event as well as prominent mention in printed materials and event advertisements. A title sponsor is added to the name of the event, such as "Bailey's American Ski Classic." Sponsorships enable marketers to leverage their marketing dollars by gaining more publicity and goodwill than those same dollars could have purchased directly. See also public relations; underwriter.
