logojets"),

seatback tray tables or overhead storage bins, taxicab doors, roof mounts and

shopping cart handles (grabertising), the opening section of
streaming audio and video, posters, and the backs of event tickets and supermarket receipts. Any place an "identified" sponsor pays to deliver their message through a medium is advertising.
Television
The TV commercial is generally considered the most effective mass-market advertising format, as is reflected by the high prices TV networks charge for commercial airtime during popular TV events. The annual Super Bowl football game in the United States is known as the most prominent advertising event on television. The average cost of a single thirty-second TV spot during this game has reached US$3 million (as of 2009).
