The World In 2007 (from the Economist) writes:
As a result, firms that used to be in separate industriestelephone operators, internet service providers and cable-TV companieshave all suddenly found themselves in the same business. Cable companies now offer broadband internet and voice services over networks that used to carry just television; telecoms firms have responded by upgrading their networks to carry television signals; and internet service providers have branched out into telephone and video services. In the new converged world, any firm that can deliver high-speed data to customers over its network can offer any or all of these services. And offering all of them together in a bundle is thought to be a winning strategy. The ultimate bundle is called the quadruple playthe combination of fixed and mobile telephony, broadband internet access and multichannel television. If your telephone company and a host of rivals are not already offering you such a bundle, you can be sure that they will start to do so in 2007.
