GEICO, with its Gecko and Maxwell the pig mascots, has been the leader in advertising spending among U.S. property/casualty insurers for at least five years through 2013, according to SNL.

GEICO is still the only company that spends more than $1 billion annually on advertising. It recorded $1.18 billion in ad spend in 2013, up from $1.12 billion in 2012.

Allstate Corp., which increased its spending on advertising 7 percent in 2013 after an 11 percent increase in 2012, has recently taken direct aim at GEICO. Its new Esurance brand commercials state that “seven and a half minutes could save you on car insurance,” a counter to GEICO’s tagline that customers can save 15 percent on insurance in 15 minutes.

State Farm Mutual Automobile Insurance Co. increased spending 3 percent to $802.8 million in 2013 following a year of negative growth. State Farm’s ad spend peaked in 2011 when it booked a 29 percent year-over-year increase to $813.5 million.
