Demand for Personal Video Recorder (PVR) products increased tremendously during the past year, as unit shipments rose from 4.6 million in 2003 to over 11.4 million in 2004, reports In-Stat. This demand stems from increased consumer awareness about the concept of time-shifting television programming, and both pay-TV service providers and PVR product manufacturers are reaping the benefits. PVR service providers, led by companies like TiVo and EchoStar, also enjoyed a banner year, as total worldwide households subscribing to a PVR service increased from 3.6 million in May 2004, to over 9.2 million in May 2005. North America remains the largest market for PVRs, followed by Japan. In 2004, the two regions accounted for 88 percent of total worldwide PVR product unit shipments. Worldwide PVR product revenues have also risen rapidly, increasing from $2.1 billion in 2003 to over $4.3 billion in 2004. A recent US consumer survey revealed that most PVR users are highly satisfied with their PVR service. Eighty-nine percent of surveyed PVR households they were either "extremely satisfied" or "very satisfied" with their PVR service.
What was once a simple, unidirectional flow of electricity from centralized power plants to passive consumers is evolving into a complex, intelligent network where millions of distributed resources actively participate in grid operations. This transformation, powered by smart grid technologies, represents one of the most significant infrastructure shifts of our time. It promises to reshape how we generate, distribute, and consume energy. At its core, the smart grid represents far more than mere digitization of existing infrastructure. This bi-directional capability is fundamental to understanding why smart grids are becoming the backbone of modern energy systems, facilitating everything from real-time demand response to the integration of renewable energy sources. Smart Grid Market Development By 2030, smart grid technologies are projected to cover nearly half of the global electrical grid, up dramatically from just 24 percent in 2025. This expansion is underpinned by explosive gr...
