Olympic broadcaster Eurosport and social media giants Facebook are among the companies to have confirmed their attendance at this year's edition of SPORTELAsia in Singapore.
Organisers of the convention, due to be held at the Shangri-La Hotel from March 13 to 15, have released the the shortlist of registered companies.
More are set to be added in the coming weeks in the build-up to the event.
Eurosport, which will broadcast Pyeongchang 2018 across Europe following an agreement signed between the International Olympic Committee (IOC) and its parent company Discovery Communications in 2015, and Facebook are among the first to sign up.
They are joined on the shortlist by Alisport, a division of IOC TOP Sponsor Alibaba, Major League Baseball and representatives from the Premier League.
World football's governing body FIFA are also due to have a presence, along with the International Tennis Federation.
SPORTELAsia organisers are expecting a rise in participants compared with the previous edition in 2016, attended by 736 representatives of 371 companies from 47 countries.
This year's convention is due to include an extended exhibition and "intense networking opportunities with Asian business partners".
SPORTELAsia is scheduled to be held two months prior to the first-ever SPORTELSummit in Miami.
The conference will gather top-level executives from relevant sports media and marketing industries, including representatives from social media, International Federations and possibly even IOC members.
It will be held annually but not always in Miami.
It was confirmed last year that SPORTEL will move away from their usual rotational model by hosting a second consecutive convention in Asia in 2019.
