cable and satellite-based services often have the channel description and programming (OSD) on the bottom of the screen. Most channels have an opaque, full-colour watermark, though exceptions exist, for example Channel 9, which displays a blue-tinted semi-transparent logo. In ad breaks, it is required to replace the channel watermark with another symbol - sometimes on the other edge of the screen - indicating there are ads at the moment. The Israel Broadcasting Authority, whose channels placed their logos in the top left corner, ceased broadcasting in May 2017. The new public broadcaster, the Israeli Public Broadcasting Corporation, displays its logos at the top right instead. The erstwhile Channel 2 as well as its successors, Keshet 12 and Reshet 13, also use the top right corner. However, Channel 10 used the top left corner before rebranding to Eser (Literally "Ten") in 2017 and simultaneously moving its logo to the top right (Not long after, in January 2019, it ceased broadcasting as it merged with Reshet 13). Channel 14 as well as its predecessor Channel 20 use the top right corner as well. The Knesset Channel, however, uses the top left corner. Italy In Italy, the channel watermark usage is different for every television network. RAI, at the end of the 1970s, introduced its first watermark, to minimize copyright infringement by private channels. The bug "jumped" around the four corners of the image. At the end of 1987, the bug added the number of the station, until 2010 in words and from 2010 in numbers. RAI's on-screen logos are not shown during news programs (e.g. TG1). RAI's on-screen logos were placed at the bottom right until 2010, much like commercial broadcaster Mediaset and commercial TV channel La7, which have always used that corner. However, during RAI's 2010 corporate rebrand, they were moved to the top right corner. During a second corporate rebrand in 2016, the logos were moved once again, this time to the top left (with some programmes having the logo on the top right corner), which has rarely been used by Italian TV networks (barring some newer channels like Discovery's Nove). On the SD feeds of RAI channels that have an HD feed, the HD channel number (starting from 501) is posted below the channel's bug. Sky Italia channels, like TV8, use the top right corner for their logos. Commercial broadcasters Mediaset and La7 have always placed their logos at
