The recent passing of TMT pioneer Steve Jobs provides an appropriate moment for reflecting on the impact that innovation in the sector has had on our lives, and how it also has driven - and outpaced - the development of the law.

Dramatic advances in microchips have fuelled the digital revolution, spawning a wide range of devices and services that our parents never could have imagined. The iPhone, the iPad, iTunes and the iPod are but a few examples of technological changes that have challenged old ways of doing business, and also have changed society. We are connected to our work and our social circles anywhere we go; we instantaneously access vast information resources from mobile devices, whenever and wherever we want.

Similarly, the Internet has changed the way people communicate, and has altered our preferences for receiving information and entertainment. Internet-based businesses have challenged traditional media businesses, such as print newspapers, print magazines, and television and radio broadcasting.

The existing telecommunications infrastructure is becoming outmoded. ‘Twisted pair’ (copper) is being bypassed in favour of fibre and wireless, as existing phone lines cannot readily support the increasing demand for broadband speeds and throughput. A robust wireless communications infrastructure is necessary to support the booming demand for mobile broadband connectivity to smart phones and tablets. As a result, government policy is evolving to support the deployment of broadband infrastructure and to facilitate the growth of mobile services; but regulatory change never seems to occur fast enough.

Historical spectrum planning did not provide for the current wireless boom. As a result, no incumbent user of spectrum is safe in the refarming of existing spectrum bands. The transition from analogue to digital signal forms is leading to more efficient use of the spectrum, and also is facilitating new approaches to sharing radio spectrum. Regulators are coming under increasing pressure to capture the value associated with the spectrum bands that are being opened for these new purposes.

The broadband revolution has eliminated one information bottleneck that once existed when consumers had to rely on a few newspapers, TV stations and radio stations. Now they are able to use Internet-based services such as Facebook and Twitter - albeit sometimes in the face of governmental attempts to stem the free flow of information to and from their jurisdictions.

We are being monitored, and our personal information is being collected, stored and mined, in a manner that regulators never envisioned and that the law is not well-suited to constrain. Virtually every Internet access and wireless device we use knows were we are, and tracks what we do. While this personal information can be used for purposes that some may find desirable, gathering and storing that information virtually eliminates any expectation of privacy. In many jurisdictions, the law is inadequate to manage the chances for abuse and the consequences of security breaches.

The Technology, Media and Telecommunications Review presents an overview of the legal constructs around the world that govern these types of issues. This second edition expands to include 30 jurisdiction chapters, each written by a recognised leader in the field. With discussions focused on recent trends, expected future developments, as well as commercial solutions, the book seeks to provide a helpful framework for further analysis.
