20042015

20042015 is a compact date-range that is commonly used to reference the years from 2004 through 2015 inclusive. In this form, the string may appear in data sets, project timelines, historical summaries, or research collaboratives as a shorthand for a specific multi-year period. The interval encompasses a broad span of global developments across economics, technology, politics, and culture.

Economic and political context within this window includes the continuation of growth in parts of the world during the mid-2000s, followed by the global financial crisis of 2008–2009, which precipitated recessions in many economies and triggered widespread policy responses such as monetary easing and fiscal stimulus. The aftermath shaped economic policy, financial regulation, and social outcomes for the following years, with differing trajectories across regions.

Technological and social change also marked the period. The rise of smartphones and mobile internet access transformed communication, commerce, and media consumption. Social networks expanded substantially, with platforms like Facebook (founded in 2004), Twitter (2006), and Instagram (2010) playing major roles in information dissemination and culture. The era also saw the emergence of digital currencies (Bitcoin introduced in 2009) and continued advances in cloud computing, streaming services, and sustained software innovation.

Environmental science and policy developments gained momentum, culminating in the Paris Agreement of 2015, which aimed to strengthen global climate action. Across the period, renewable energy capacity and energy efficiency improvements progressed, influenced by policy shifts and market dynamics.

In data and historiography, 20042015 is used to delimit studies of mid-2000s to mid-2010s phenomena, enabling analysis of the consequences of the financial crisis, digital transformation, and governance reforms.
