Side-by-side is a type of split-screen presentation format used on television broadcasts, particularly as a means of continuing to show a view of ongoing live content, whilst simultaneously airing commercials alongside them. Typically, only the audio of the advertising is played.
The practice was initially synonymous with sporting events, with TBS first using the format in a 2000 NASCAR Cup Series race. Motorsport is one of several sports that do not have natural television timeouts; as races are only typically halted for reasons such as accident cleanup and inclement weather, there are no natural locations for commercial breaks besides caution periods — which vary based on race conditions (although under current NASCAR regulations, all races are guaranteed to contain two competition cautions due to their new stage system).
The technology uses a split-screen to show the feed of the live sports event on one side with no audio, while the traditional commercial is placed on the other side, with full audio. Typically, the square used for the commercial is larger and more prominent than that of the event. Sometimes, a small graphic showing the lap count and leaders' names accompanies the square, or the normal ticker is still shown in the layout. side-by-side is used during all national commercial breaks during the race but Side-by-Side is also used during local breaks.[1] Side-By-Side can also be used during the pre-race and the post-race segments. During red flag stoppage conditions, Side-by-Side has been used, but during lengthy delays, such as rain delay, commercials revert to traditional full-screen format.
The concept has since been adopted, at times, in other sports such as golf, as well as football and other non-sports events: although there are natural breaks in football, the content displayed in the live view may consist of behind-the-scenes content.
