Proposed Addition to LHC Computing Grid. Any comments would be appreciated.
The Worldwide LHC Computing Grid (WLCG) – a distributed computing infrastructure arranged in tiers – gives a community of thousands of physicists near real-time access to LHC data. The Worldwide LHC Computing Grid (WLCG) is a global collaboration of computer centres.

2008 Media Coverage Confusing. The Worldwide LHC Computing Grid (WLCG) is a global collaboration of computer centres. did not exist We had to invent all of the tools from scratch At CERN we had no tools to manage a data centre at the scale we thought was needed (no commercial or OS tools existed) Initial tools developed through EU Data Grid – Open Source from the beginning When we started LHC computing (~2001) There were no internet companies, no cloud computing – Google was a search engine, Amazon, etc.
EGI currently involves more than 240 institutions in 45 countries, supporting science in more than 20 disciplines, including bioinformatics, medical imaging, education, climate change, energy, agriculture and more. The Worldwide LHC Computing Grid, or WLCG , is unique in a number of important respects. The CERN data centre is at the heart of WLCG, the first point of contact between experimental data from the LHC and the grid. It was launched in 2002 to provide a resource to store, distribute and analyse the 15 petabytes (15 million gigabytes) of data generated every year by the Large Hadron Collider (LHC).

In 2008 there was widespread media coverage that reported that the …

The following is suggested text for an additional section to the Wikipedia article.

Firstly, it does not actually exist as such, but is built upon existing Grid infrastructures—primarily the OpenScience Grid (OSG [2] ) in the US and the Enabling Grid for E-sciencE (EGEE [3] ) in Europe and elsewhere.

It was launched in 2002 to provide a resource to store, distribute and analyse the 15 petabytes (15 million gigabytes) of data generated every year by the Large Hadron Collider (LHC).. The Worldwide LHC Computing Grid has been the driving force behind the European multi-science European Grid Infrastructure , which continues to grow in size and diversity of usage.
