Today is the 53rd Superbowl. Inc announced the 3 contestants named for Super Bowl Small Business Ads, so viewers can watch for them. Atlanta’s restaurants, retailers, and many small businesses are expected to be beneficiaries of this event. But small businesses everywhere may benefit (last year each adult spent over $80 in preparation of the Super Bowl). And homeowners in Atlanta may have great windfalls, with Airbnb listings of a $1,000 to $1,200 per night. Note: If a home’s annual rental does not exceed 14 days, the rental income is tax free, regardless of the dollar amount.
