The event, being held in association with law firm Addleshaw Goddard on October 13, has a waiting list of delegates.
"The opportunities presented by new technologies and the quality of the speakers we have assembled have encouraged delegates to join us from as far away as Brazil," said publishing director Andy Rice.
"We are delighted with the response and we are looking at ways to stream the event, taking it to a wider audience."
BT recently joined sponsors txt Station, Sportev and Dreamteam Interactive in an effort to use the event to introduce revenue-generating innovation to the sports industry.
