Plans include extending ultrafast broadband to an extra 230,000 residential and 55,000 business premises by 2015.
Ms Miller said: "Fast broadband is essential for growth and is key to the country's economic future. These 10 cities have produced ambitious and comprehensive plans which will turn them into digital leaders and give their local economies a real boost.
"The new investment will help put these cities at the centre of the digital stage, competing for jobs and investment with the best in the world."
A second £50 million fund was announced in the Budget to be shared between 10 smaller cities.
