Yes I do think that Domino's can continue to gain in the pizza franchise market. In my small town Domino's is actually the only pizza franchise restaurant we have available. They are constantly coming up with new ideas such as the toppings on the chicken. They also have a fair amount of options.
Domino's Pizza has been on a hot streak recently and this will continue. Domino's has realized that they need to honest and upfront and listen to their customers. They have shown a willingness to do this with their recent change to their ingredients used on their pizzas. They have also shown that they are looking toward the future with the introduction of a great new pizza ordering app. Their app is really the leading app for pizza chains and shows that Domino's is making a significant effort to reach out to their target consumers, and will continue to do so.
Domino's Pizza is still the first name that people think of when they think of home delivered pizza. While Pizza Hut and others may have similar or even greater name brand recognition, Domino's is still the most well-known delivery brand, and as such, should continue to propser as more people choose to eat at home instead of out of the house.
Domino's name will carry them and they can continue to gain. This is because familiarity breeds comfort in a lot of people. Food trends come and go, but chains tend to still stay around out of people's habits and memories of good tasting food. The food industry spurs a lot of success with pizza franchises.
