History
Antiques Trade Gazette was founded in September 1971 in London by journalist Ivor Turnbull, previously diarist at the Evening Standard and editor of Art and Antiques Weekly. It provided a calendar of art and antiques sales, and was initially resented by many antique dealers keen to protect their favourite country sales. However, it eventually became an essential tool of the trade - being described by the Burlington Magazine as the "acknowledged 'Bible' of the fine art and antiques industry".

The Gazette's publisher, Metropress, was acquired by the Daily Mail and General Trust in 1994. The company adapted to the internet, creating the-saleroom.com, before, in 2006, launching a live bidding platform, the latest step in its transition from print to an internet offering. In October 2008, when the business had 53 staff and a turnover of £6 million, it was the subject of a management buyout backed by private equity house Matrix (today Mobeus Equity Partners). The deal also saw the company divest three US-based publications AntiqueWeek, AntiqueWest and Auction Exchange.

From 15 percent of sales at the time of the MBO in 2008, the-saleroom.com revenues accounted for 45 per cent of the business's £8.9 million turnover by 2012. The company offered its antique bidding platform to publishers in Germany and France, and invested in China’s live auction site, epai.hk. It also established a separate auction site, ibidder.com, focused on industrial equipment.

Private equity firm ECI Partners invested in the business in 2014, by which time the website sold £68.3 million of art and antiques, while ibidder.com saw sales worth £39.4m, generating revenues of over £15 million. The company renamed itself from ATG Media to Auction Technology Group in November 2016. TA Associates acquired a majority stake in the company in February 2020 with existing investor, ECI Partners, reinvesting from its latest fund and holding a minority stake.

On 8 February 2021, the company, chaired by Breon Corcoran, announced plans to float in the London Stock Exchange through an IPO in March 2021.
