October marks National Pizza Month and brands like DiGiorno, California Pizza Kitchen and Pieology are baking up mobile and social activations to give Americans what they want—free pizza. 

Frozen pizza brand DiGiorno is breaking the ice by delivering free pizzas to five cities across the US, making a limited number of deliveries to one city each week of the month. Starting at midnight on October 1, DiGiornio is asking fans to help crowdsource two additional delivery locations by tweeting the name of their city using the hashtag #DeliverDiGiorno. The two cities that get the most mentions on Twitter will receive free oven-ready pizza delivered. To further celebrate its free deliveries, DiGiorno’s Twitter will feature a new customized tagline and logo throughout National Pizza Month.

California Pizza Kitchen (CPK) and Grubhub are keeping the pizza party going with a partnership that’ll give away up to 10,000 free CPK take and bake pizzas, which the brand launched at CPK locations nationwide in July. CPK is also offering free delivery and one free take and bake pizza on all $15 minimum purchases via Grubhub. Underpinning CPK’s National Pizza Month activation is its third annual national pizza survey which found that Americans would choose pizza if they could only eat one food for the rest of their lives.

Conducted online via The Harris Poll, from August 26-28, the survey revealed that 40 percent of Americans would be willing to give up dating for a year in order to enjoy free pizza whenever they want. Similarly, 61 percent of millennials said they’d give up social media for an entire year just to have access to free pizza at all times. Respondents included 2,014 Americans ages 18 and older among whom 632 are 23-38 years old. 

Pieology is also sharing a slice of its pie with a month-long national sweepstake, “Scan, Score & More.” One grand prize winner will win free pizza for a year per restaurant at each of the brand’s domestic locations across the US, including Hawaii and Guam. Fifty runner-up winners will win prizes including tickets to Six Flags theme parks and movie tickets. For a chance to win prizes, fans must check-in at their local Pieology via the “Pie Life Rewards” app. Pieology has over 100 locations in the US.
