Technology advertising page volume trends continued to improve and yields are ahead of expectations. Exhibitions and online also made important positive contributions to CMP Media's second-half year-on-year growth.
The trading update came as UBM, which owns the NOP World research business, spent £23m acquiring Italy's largest independent market research company Eurisko.
Eurisko offers a range of syndicated and custom research products and consulting services, and shares with NOP World a leading position in the automotive, financial services, healthcare and media sectors in their respective markets.
In a statement, UMB said that through Eurisko, NOP World can now market its key products directly into Italy and can offer a wider geographical presence to its multinational clients.
Lord Clive Hollick, CEO of UBM, said: "Eurisko is attractive strategically, financially and geographically. It complements NOP World's existing sector strengths and gives NOP World a leading presence in one of the major European markets."
