UBM plc was a British business-to-business (B2B) events organiser headquartered in London, England, before its acquisition by Informa in 2018.

Its main focus was on B2B events, but its principal operations included live media and business-to-business communications, marketing services and data provision, and it principally served the technology, healthcare, trade and transport, ingredients and fashion industries.

[12] The stake in Yorkshire Tyne Tees Television was sold to Granada, allowing them to take control of the two franchises in 1997.

The channel was put up for sale in 2001, and was eventually brought by Edinburgh-based company Power TV a year later, in April 2002.

[15] In 1999, plans emerged of a merger between UNM and rival Carlton,[16] however these talks failed when it appeared that Meridian would have to be sold off as a condition of the deal.

[17][18] As a result, the television assets of UNM were sold to Granada, however due to regulations stating that the company could not control that large an audience share, the broadcasting arm of HTV was sold to Carlton in exchange for Central's 20% stake in Meridian.

[43] In June 2016 UBM plc announced the completion of the sale of PR Newswire to Cision.

The portfolio comprised the US and Asian versions of EE Times, EDN, ESM, Embedded, EBN, TechOnline and Datasheets.com.
