Some 190,000 Welsh homes and businesses are now able to access super-fast fibre broadband as a result of the Superfast Cymru programme.
The rollout - which is being supported by public and private funding - is continuing apace in rural parts of Wales that have been overlooked by commercial operators.
By spring 2016, the Welsh Government is aiming to offer 80Mb download speeds to 96 per cent of premises across the country.
Ken Skates, Deputy Minister for Skills and Technology, said super-fast broadband "has the ability to transform the way we live our lives".
"From accessing entertainment and communicating through social media to how businesses interact with customers and develop ways of working more efficiently, fast fibre broadband opens up a whole spectrum of opportunities," he claimed.
Mr Skates said the Welsh Government is "fully committed" to seeing Wales become a truly digital nation.
Ensuring it has the right infrastructure in place is "vital" in making that vision a reality, he claimed.
"Our plans for super-fast broadband are the most ambitious in the UK, providing faster broadband to a greater proportion of premises more quickly," Mr Skates stated.
He said he is "very pleased" that 100 exchange areas are now live in Wales thanks to the Superfast Cymru programme.
This means thousands of people can enjoy the benefits of faster internet speeds, Mr Skates noted.
"The project continues at pace and will reach more communities and make a significant difference to businesses and households," he added.
The Welsh Government, the UK Government and the European Union have committed a combined £205 million to the Superfast Cymru programme.
In addition to this, BT - the private sector infrastructure partner - is investing £220 million in super-fast broadband networks for rural Wales.
