Previously, advertisers who wanted to target financial workers had to buy individual formats.
The Canary Wharf and City Pack has a total 362 sites - 133 in and around the City and 224 in Canary Wharf and its vicinity. They include six-sheets, Mega six-sheets, 96-sheets, Mega 96-sheets and Magink Digital billboards.
Clear Channel believes the pack will attract brands from the financial services, telecoms, airline and luxury retail sectors.
But it also hopes to appeal to property agencies, health facilities, car companies and online retailers.
Financial workers are light TV viewers and radio listeners, and are 70% more likely to be heavily exposed to outdoor advertising, according to research from TGI.
The pack will complement Clear Channel-owned Taxi Media's London Commuter and Business and Finance packs.
