Changing work and play - Industry Crossovers

With IP the common denominator, companies are crossing into new industries and businesses, colliding as well as cooperating in staking out their digital turf.

Television, music and computer companies are increasingly focusing on mobile phones as the next entertainment platform. Examples include MTV's alliance with Sprint and Google's relationship with CBS.

This crossover world was envisioned in the 1990s by computer pioneer Gordon Bell, who painted a picture of the colliding worlds of telephony, television and computing. This "triple play," which is often extended to the quadruple play when mobility is added, is obliterating stovepipe companies and services of the past, while ushering in new multi-service scenarios.
