About tennisnet.com

tennisnet.com

tennisnet.com is a German-language tennis portal operated from Vienna, Austria, by A Team Media GmbH. It was launched in May 2010 by two former professional players, the Austrian Alexander Antonitsch and the German Carl-Uwe Steeb, who set out to build a dedicated home for tennis news in the German-speaking market rather than a general sports site with a tennis section. By the time of its tenth anniversary the portal was described by its owners as the largest and highest-reach tennis portal in the DACH region of Germany, Austria and Switzerland, credited in a January 2021 ownership announcement with 4.5 million unique clients and 14 million visits per year, growth its owners linked to the successes of Dominic Thiem and Alexander Zverev. On 1 January 2021 the publisher missMEDIA took a 50 percent stake in A Team Media, forming a 50:50 joint venture with the Antonitsch consortium, a structure intended to push the portal's social media, search visibility, native advertising and e-commerce development.

Launch in May 2010 by two former professionals

The founding is documented in the biographical record of Alexander Antonitsch, which records that in May 2010 he launched the website tennisnet.com together with the German former world-class player Carl-Uwe Steeb. The pairing was the portal's original credential: its founders had played the professional game at the highest level and could present the site to readers, players and advertisers as a product made from inside the sport. The operating company recorded for the portal is A Team Media GmbH, based in Vienna, which anchors this profile geographically in the Austrian capital even though the portal's reporting and audience have always addressed the whole German-language tennis market across Austria, Germany and Switzerland.

Alexander Antonitsch, founder and managing director

Antonitsch's playing record explains the authority the portal claimed. Born on 8 February 1966 in Villach, he turned professional in 1988, won one ATP singles title at Seoul in 1990 and four doubles titles, and reached his career-high singles ranking of world number 40 on 9 July 1990, the year he also reached the fourth round at Wimbledon and the semi-finals of the Davis Cup with Austria. After his playing career he worked for the promotion of young players, founded the Tennis4Kids school sport initiative in Vienna, worked as a co-commentator for Austrian television until 2013, became tournament director of the Generali Open in Kitzbuehel in 2011, and has commentated on Grand Slam tennis for Eurosport since the US Open 2013 and for ServusTV since the Australian Open 2019. When the 2021 ownership change was announced, Antonitsch was identified as the managing director of tennisnet.com, speaking for the portal about its strategy. His continuing public roles in Austrian tennis, in the media and at Kitzbuehel kept the portal's founder visibly inside the sport it covered.

What a dedicated tennis portal offered

The concept behind tennisnet.com was specialisation. General sports media in the German-language market are dominated by football, and tennis coverage within them expands during Grand Slam tournaments and contracts between them. A standalone portal could follow the ATP and WTA tours continuously, serve committed fans between the major events, and offer advertisers a defined target medium for a single sport, which is exactly how its owners described it in 2021: the strongest-reach digital target-group medium for tennis in the DACH region. The Vienna operation therefore competed less with Austrian general news sites than with the tennis verticals of large German and Austrian sports publishers, and its founders' playing backgrounds gave it a claim to expertise that a generalist brand could not easily copy. Precise details of its day-to-day editorial staffing across the years are not documented in the sources verified for this profile, and no staffing figures are asserted here.

Growth and the Thiem and Zverev effect

The portal's growth story, as told by its owners in January 2021, is inseparable from the players of its era. The announcement stated that the recent successes of Dominic Thiem of Austria and Alexander Zverev of Germany continually fuelled the tennis boom in Austria and Germany, and it quantified the result at that moment as 4.5 million unique clients and 14 million visits per year, calling tennisnet.com the largest tennis portal in the DACH region. Those figures are reproduced here as the company's own description at the time of the ownership announcement, not as independently audited current traffic, and readers should treat them as a dated snapshot from the portal's tenth-anniversary period rather than a live measure. The underlying sporting context, however, is a matter of record: Thiem had become Austria's first Grand Slam singles champion of the modern era's dominant generation and a fixture at the top of the rankings, and coverage demand for German-language tennis reporting rose with him, to the benefit of the specialist portal that Austrian tennis fans already knew from its founder's name.

Styria's earlier role in the ownership

Before 2021 the majority owner of A Team Media was the Styria media group's sports company, STYRIA Medienhaus Sport GmbH und Co KG. The January 2021 announcement described the change explicitly as missMEDIA taking over, with effect from 1 January 2021, the Styria company's share in what it called the largest tennis portal of the DACH region. The detail matters for the portal's history because it marks a change of strategic home: from a large traditional publishing house, whose sports portfolio held the portal through its first decade, to a smaller digital publisher that promised movement after what Antonitsch himself described as years of strategic standstill. The remaining small percentage of the Styria holding did not go to missMEDIA but to the shareholder circle around Antonitsch, a detail that balanced the resulting shareholding precisely.

The missMEDIA joint venture of 2021

The transaction was announced on 12 January 2021 with effect from 1 January 2021. missMEDIA GmbH acquired 50 percent of A Team Media GmbH, taking the greater part of the former majority holding of Styria Medienhaus Sport, while the rest of the Styria percentage passed to the consortium around former professional Alexander Antonitsch, whose members were named as Harald Buchheister, Markus Houben and Harald Schroeder alongside Antonitsch himself. The result was a 50:50 joint venture between the Antonitsch consortium and missMEDIA. Management of A Team Media was completed by Jochen Hahn, who served in parallel as managing director of missMEDIA. Antonitsch welcomed the change in the announcement's own terms, saying that after years of strategic standstill the portal now had a co-owner who could fire up the decisive future topics.

Strategy after 2021: reach, native advertising and commerce

The stated future focus of the joint venture was growth in reach and native advertising, and Antonitsch specified the agenda as social media, search engine optimisation and native marketing in the coming months, calling it the perfect set-up for the portal's tenth anniversary. Beyond that, tennisnet.com was to be used as a vehicle for e-commerce and customer-specific performance campaigns. That programme describes the standard economics of a specialist digital publisher of its period: a defined, affluent sporting audience, monetised not only through display advertising but through sponsored content formats, search-driven traffic growth and direct commercial partnerships built on the audience's loyalty to a single sport. The sources consulted for this profile document this strategy as announced intention in January 2021; they do not provide independently verified results for the years that followed, and this profile makes no claim about how fully each element was realised.

Position in the DACH tennis media market

Within Austria, tennisnet.com occupies a niche that no general outlet fills: it is a Vienna-operated, German-language, single-sport portal whose founders and public face come from professional tennis itself. Its documented milestones are consistent and checkable: launch in May 2010 by Antonitsch and Steeb, a decade of operation under majority Styria ownership, the self-described market-leading DACH reach announced in 2021, and the rebalancing into a 50:50 venture between its founder's consortium and missMEDIA. For Austrian readers its significance is doubled by Antonitsch's other roles, since the same figure directed the country's biggest home tournament at Kitzbuehel and commentated on Grand Slams for Eurosport and ServusTV, weaving the portal into the fabric of how tennis is presented in Austria.

Reading the record with care

A final note on evidence: tennisnet.com has never attracted the volume of independent reference coverage that Austria's general news portals receive, and much of what is verifiable about it comes from two kinds of sources, the biographical record of its founder and the company's own ownership announcement of January 2021. Both are solid for the facts they state, and this profile has confined itself to those facts, attributing reach claims to the company and its date rather than presenting them as current or audited. No reliable verified source consulted for this profile documents a closure, a later change of ownership after the 2021 joint venture, or a complete editorial staff list, so none is asserted. On the documented record, tennisnet.com stands as the Austrian-founded specialist that turned two professional playing careers into the German-speaking region's dedicated tennis news home.
