Brazilian fast-food chain Bob's, the largest competitor to McDonald's in that country, offered, since 1959, milkshakes and sundaes made with Ovaltine, where it goes by the name of "Ovomaltine", which became a flagship product of the fast-food chain in Brazil. In 2016, McDonald's acquired exclusive rights to sell "Ovomaltine"-branded milkshakes. Brazil has the second largest Ovaltine factory, in São Paulo, and is the second largest consumer market for the product, after Thailand. The Brazilian Ovaltine is unlike any other in the world, originating from an assembly line malfunction that made the powder crispier that is still maintained today.
