Basic Research, L. L. C., advertised its products on television networks owned by Rainbow Media Holdings, Inc., through an ad agency, Icebox Advertising, Inc. As Basic’s agent, Icebox had the express authority to buy ads from Rainbow on Basic’s behalf, but the authority was limited to buying ads with cash in advance. Despite this limit, Rainbow sold ads to Basic through Icebox on credit. Basic paid Icebox for the ads, but Icebox did not pass all of the payments on to Rainbow. Icebox filed for bankruptcy. Can Rainbow recoup the unpaid amounts from Basic? Explain.
