feed rather than distinct feeds for both formats, most broadcast networks dropped HD-specific logo bugs and used bugs in the 4:3 safe zone for all viewers, regardless of feed. By 2018, most bugs and on-air presentations have been oriented exclusively for 16:9 framing. The inclusion of text advertisements for upcoming programs alongside the bug is also particularly prevalent among some broadcasters. Since the mid-2000s, some stations and networks showed their websites alongside their bugs, especially during newscasts. National morning shows like Today and Good Morning America'' have also shown their specific websites rather than their network's main website in addition to the bug that shows their program. Beginning in 2010, some networks began to display show-specific hashtags alongside their bugs, which encourage viewers to discuss and interact with the program online via social networking services such as Twitter. Vietnam Vietnamese TV stations started showing their digital on-screen graphical DOGs in 1995. Logos are not removed during commercial breaks, but remain in full-color, unlike their counterparts in Indonesia. A digital clock and programme name may also be shown. Some cable channels show its cable provider logo and its logo. For example, VTV Cable's channels has the logo of the cable provider on the top-left, and the channel logo on the top-right. Other providers and international channels were in the top-right, while K+ in VTV Cable bug used in the bottom-left. Connections with sponsor tags Another graphic on television usually connected with sports (particularly in North America, though not in Europe) is the sponsor tag. It shows the logos of certain sponsors, accompanied by some background relevant to the game, the network logo, announcement and music of some kind. Usage in ham radio and TV In most countries, the ham station is required to periodically identify their amateur-TV transmission. Such stations frequently overlay their callsign on the signal instead of placing a card in the background. Most hams use homebuilt devices or old consumer character generators to generate such identifications rather than using graphical superimposes of high cost to do so. Only rarely one can see real graphics, as the callsign is usually written in the "OSD font". Live DOGs by hobbyists One of the easiest and most sought-after devices used to generate DOGs by hobbyists is the 1980s vintage Sony XV-T500 video superimposer. This device can luma-key a signal, capture a still frame into memory and then overlay the keyed graphic
