# Top 30 media companies and publishers in London

Tamtam tracks 262 media companies and publishers headquartered in London. This list ranks the 30 largest by number of employees on LinkedIn, led by BBC, RELX and Pearson. Their median headcount is 4,926. Half of them were founded in 1982 or later.

These London-based companies primarily operate in media production and distribution, information services, and publishing. The list includes large, established organizations like the BBC, a public service broadcaster, and RELX, a global provider of information-based analytics. Other significant firms are Pearson, a leader in learning content, and Informa, which specializes in events, digital services, and academic knowledge.

A notable pattern is the dominance of broadcast media, with several BBC divisions (BBC News, BBC Studios) alongside ITV and Formula 1. Many of these companies have a long history, such as The Economist, founded in 1843, indicating a mature and well-established media sector in London.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
