Global broadband adoption continued to increase during the first three months of 2012, it has been reported.
Research published by the Broadband Forum indicated that 16.1 million new lines were added worldwide between January and March, taking the total to 613 million.
Over 100 million fixed connections have now been added in the last 18 months, the body noted.
The growth rate also accelerated during Q1 2012, with the number of subscribers some way up on the 14 million added during the final three months of 2011.
Robin Mersh, Chief Executive of the Broadband Forum, said another "significant milestone" had been reached in "an exciting arena that shows no sign of slowing down".
"It is just 18 months since we celebrated the 500 million subscriber watershed," he noted
Mr Mersh said he was particularly pleased with the increase in fibre broadband penetration during Q1 2012, with strong demand witnessed for both hybrid and fibre-to-the-home connections.
