pizza came first, by 189 years. Tomato-topped flatbread was being sold in Naples.

the internet (ARPANET)

On 29 October 1969 a team at UCLA tried to send the word "login" to Stanford. The system crashed after two characters, so the first message ever sent over the internet's ancestor was "lo". By the end of that year the network had four nodes. The internet is twenty years older than the Web, and confusing the two is the single most common error in this whole subject.

pizza

Flatbreads with toppings are ancient, but pizza in the sense people mean — wheat base, tomato, baked in a wood oven — dates from Naples in the late 1700s, and could not have existed earlier because tomatoes only reached Europe from the Americas in the 16th century and were widely thought poisonous for two hundred years. The Margherita story, in which a Naples pizzaiolo created a red, white and green pizza for Queen Margherita in 1889, rests on a single document now widely believed to be a forgery. The first American pizzeria, Lombardi's in New York, was licensed in 1905.
