The Pizza Hut app will be available starting today, and is viewed by the pizza company as a logical extension of their online ordering service. It has been possible to order Pizza Hut online since way back in 1994 (making online pizza older than many modern gamers, what a horrifying thought) and the service was expanded out into the wider digital landscape with apps as the technology became available.
While some people are skeptical that an Xbox app is actually necessary or likely to result in any real increase in sales, as a gamer I can attest that having a new way of ordering pizza is never a bad thing. The important capability this app provides is the ability to order without meaningfully interrupting the gaming a person is in the middle of, and that is not something so easily quantified.
