Commercial skipping is a feature of some digital video recorders that makes it possible to automatically skip commercials in recorded programs. This feature created controversy, with major television networks and movie studios claiming it violates copyright and should be banned.
For many years, video recorders manufactured for the Japanese market have been able to skip advertisements automatically, which is done by detecting when foreign language audio overdub tracks provided for many programmes go silent, as advertisements were broadcast with a single language only.
The first DVR which had a built-in Commercial skipping feature was ReplayTV with its "4000 Series" and "5000 Series" units. In 2002 five owners of the ReplayTV DVR sued the main television networks and movie studios, asking the federal judge to uphold consumers' rights to record TV shows and skip commercials claiming that features like commercial skipping help parents protect their kids from excessive consumerism. ReplayTV ended up filing for bankruptcy in 2003 after fighting a copyright infringement suit over the ReplayTV's ability to skip commercials.
In addition to the PVR devices which existed in the private market since the late 1990s, towards the mid-2000s (decade), due to the significant advances in home computers, Home theater PCs started gaining popularity in the private market and many users began using their Home theater PCs in their living room for entertainment purposes.
Following this, many PVR programs were developed, including popular programs such as Windows Media Center, which contained all of the features of the PVR devices in addition to advanced features such as HDTV and the use of Multiple TV Tuner Cards. Some independent developers began developing independent software capable of skipping the commercial segments when playing recorded videos, and permanently removing the commercial segments from recorded video files.
By 2014 many PVR programs such as Windows Media Center, SageTV and MythTV had the capability to skip commercials segments in recorded TV broadcasts after installing third-party add-ons such as DVRMSToolbox, Comskip and ShowAnalyzer, which use various advanced techniques to locate the commercial segments in the video files and save their locations to text files. The text files can also be fed into programs such as MEncoder or DVRMSToolboxGUI which can delete the commercial segments from the recorded video files.
A few third-party tools such as MCEBuddy automate detection and removal of commercials.
One of the major weaknesses of commercial skippers is that, operating automatically, they may misidentify program material as a commercial and delete it. Most third-party programs do not allow manual fine-tuning of commercial segments locations before deletion.
In May 2012 the US Dish Network began offering a DVR with what it calls AutoHop. The device would automatically skip commercials when displaying programming that the viewer had previously recorded with the PrimeTime Anytime feature. It does not skip ads on any live programs. US broadcasters were angered at the news, and FOX embarked on legal action.
The introduction of digital video recorders and services with skipping and fast-forward facilities enable viewers to avoid viewing advertisements in recorded programs, either manually or automatically. In addition to separate television advertisements which can be skipped, advertising in TV shows themselves ("product placement") is possible, and cannot be skipped. Streaming services such as Hulu show shorter advertisements with a countdown timer and tailored to the viewers interests, asking interactive questions like "Is this ad relevant to you?".
