Just pay a homeless guy to run around on the field naked with nothing on but a Gameznflix banner flapping behind him. We would get national exposure, and it would only be the cost of a ticket, and a GZFX banner...
funny you should say that... did you know thats illegal? A study done a long time ago suggested that if something were flashed on a screen in front of a large audience, the audience would pick up on it subconciously and then act on it later. this was tested in a movie theater, in which one frame of a movie was replaced with "buy more popcorn". It is said that popcorn sales after the movie spiked after this test, and so the goverment has outlawed this type of advertisment.
