Digital economy think tank IDATE has published the 14th edition of its DigiWorld Yearbook, "the international reference for the current state of the digital world".

The Yearbook includes the latest developments and insights into the telecoms, internet and digital media markets. This year’s edition answers questions such as how are the key digital sectors such as telecoms, digital media and the Internet of Things evolving, and can Europe’s ailing telcos turn things around?

It also addresses the future of the content industries, and what forces will influence the internet’s development towards 2025.

IDATE CEO Yves Gassot said: “A bumper crop of events unfurled in 2013 and the early months of 2014, hinting at what the future might hold for digital industry markets. Mobility, the cloud and big data are the core issues up for debate amongst digital ecosystem stakeholders.”

The Yearbook says DigiWorld markets saw an uptick in growth in 2013, rising from 2.8% in 2012 to 3.2 %, generating close to just under €3,500 billion (£2,868 billion) in global revenues. This figure includes revenues for telecoms equipment and services; IT hardware, software and services; consumer electronics; and TV revenues.

Internet services - which separately saw total global sales of €221 billion in 2013 - enjoyed much higher growth rates. As part of this market social media sites, mobile apps and OTT (over-the-top) video have shown rises of between 30% -plus and 50% over the last three years.

The cloud is another big source of growth, with revenue rising by close to 30% per annum, and it single-handedly accounts for more than a quarter of online revenue.

Equipment global growth in core DigiWorld markets in 2013 varied from segment to segment, ranging from 6.2 percent for telecoms hardware to -5 percent for consumer electronics.

Telecoms services continue to linger at the bottom, with a growth rate that has been shrinking for the past five years, and dropping to 2.5% in 2013. There was 4.5% growth for IT and software, and 4.4 percent for TV services.
