Salford is an area of Greater Manchester, England, west of Manchester city centre in a meander of the River Irwell, which forms part of its boundary with Manchester. Historically in Lancashire, Salford was the judicial seat of the ancient hundred of Salfordshire. It was granted a charter by Ranulf de Blondeville, 6th Earl of Chester, in about 1230, making Salford a free borough of greater cultural and commercial importance than its neighbour Manchester, although since the Industrial Revolution of the late 18th and early 19th centuries that position has been reversed. Salford is home to the University of Salford, and has seen several firsts, including the world's first free public library, and the first street to be lit by gas. Salford's MediaCityUK became the headquarters of CBBC and BBC Sport in 2011, joined by ITV Granada in 2013.
