“The telecommunications industry has experienced more change in the last decade than in its entire history,” says IBM Institute for Business.

Consider that, in 1999, only 15 percent of the world’s population had access to a telephone; by 2009, nearly 70 percent had mobile phone subscriptions. If that seems unremarkable, consider that it took 150 years to add the first billion phone users. Then it took a decade to add the second billion users.

So where will the industry be in five years, in 2015? While nothing is certain, forecasters at the IBM Institute for Business Value say they see four possible outcomes, and none of them are rosy for the telecom business.

Keep in mind IBM believes it will take only five years for one of these scenarios to develop.

Scenario 1 – Survivor Consolidation:
Consumer spending for communications drops, leading to industry “stagnation or decline.”
In this rather-bleak scenario, developed market operators have not significantly changed their voice communications and “closed” connectivity service portfolios and also have failed to expand horizontally or into new verticals. That will trigger an Investor loss of confidence in the telecommunications sector, which produces a cash crisis and leads to industry consolidation.

Scenario 2 – Market Shakeout
Carriers are structurally reshaped into separate wholesale and retail businesses, and the market is further fragmented by government, municipality and alternative providers.
 In this scenario private capital is available only to dense urban areas. Telecom provider growth occurs in large part through sales of services to business partners.

Scenario 3 – Clash of Giants�
Carriers consolidate, cooperate and create alliances to compete with “over the top” providers and device manufacturers or even equipment suppliers.

Scenario 4 – Generative Bazaar
Open access infrastructure leads to more competition from “asset light” and over the top competitors.

It is easy to dismiss the level of change the last 10 years has wrought. It might be easy to dismiss the level of change IBM believes can happen in just another five years. As always, the forecast might be too aggressive in terms of its timetable.

The major implication, though, is that the telecom industry might well be a very-different sort of business by 2020, if not by 2015. If you look at revenue sources, it is virtually certain that in developed markets, less revenue–in some cases far less revenue–will be earned from voice and text services.

More revenue will be earned from broadband services, and possibly from business partners rather than end users.

Under such circumstances, ecosystem conflict is all but inevitable.
