In a campaign celebrating 20 years of digital ordering, Pizza Hut highlights its history of digital milestones, starting with its first online order.

The ability for customers to order delivery is key to many pizza chains, with some of them on the forefront not just of online ordering, but the changing digital landscape.

Just last year, Pizza Hut garnered attention when it looked for a digital marketing manager with Twitter-like pitches. The chain also used streaming media to create a pizza ordering app for Xbox Live, an online network available through the Xbox video game console.
