TV Tokyo also runs the TX Network, Japan's smallest station network consisting of TV Tokyo themselves, serving the wider Kanto region, alongside five affiliates in five prefectures in Japan.

Since other broadcasters such as Fuji Television, TBS, Nippon Television and TV Asahi were restructured as the corporate functions were moved to certified holding company statuses with the broadcasting operations taken over by wholly-owned subsidiaries, TV Tokyo is the only broadcaster in Japan (as of 2023) to keep its corporate functions after the merger with TXBB and BS Japan was completed, due to the broadcaster's relationship with Nikkei as well as having only six affiliates in its network, which also held shares in TV Tokyo and the affiliates themselves.

On March 29, 2010, TV Tokyo Corporation, TV Tokyo Broadband and BS Japan announced that it would form a joint holding company, which would merge its businesses.

One of the reasons TXHD was formed was due to the companies' plans to improve its management efficiency as well as the emergence of video services in Japan at that time.
