Advertising during a live sports broadcast on TV can be a goldmine -- and it's not limited to just throwing up a 30-second commercial between quarters. There are tons of fun and creative ways that companies can get their brand some extra face time on the screen. Take a look at some of these examples. Allstate has been a major sponsor for college football for years. Every time a field goal or extra point is kicked, you can see their logo promineintly displayed in the net that catches the ball. I've always thought this was a great use of their message "You're in good hands with Allstate." During a Big East basketball game at Seton Hall last week, Gatorade purchased the first few rows of each section stretching the length of the court then covered them with tarps displaying their trademark 'G'. BONUS: It's pretty tough to miss the rotating signage at the scorers table showing Prudential's logo at this particular moment. McDonald's covered the STAIRS with golden arches at a recent University of Minnesota basketball game. Also at the University of Minnesota, Arby's shows off a giant logo beneath the hanging scoreboard at mid-court. Clearly fast food chains love to advertise at University of Minnesota basketball games because here's ANOTHER one -- Dairy Queen displays the DQ lips on the padding at the bottom of each basket.
