Zattoo is a TV platform for IP-based transmission of television channels and video on demand content to a variety of devices. The company headquarters are located in Zurich and it has additional offices in Berlin, Ann Arbor (USA) and Singapore. Zattoo is operational in two business areas - in addition to its own B2C TV streaming operations aimed at end customers in countries such as Germany and Switzerland, Zattoo has a strong B2B business and is a leading partner for telecommunication companies worldwide.
With roughly 20 million registered users, Zattoo is the biggest TV-streaming provider in Europe. Live TV and on-demand content can be watched via Zattoo on computers and smartphones (iPhone, Android, Windows 10) and on tablets (iPad, Android, Windows 10). Zattoo also offers TV applications for televisions with integrated internet connectivity such as the Samsung Smart TV, Xbox One, Amazon Fire TV, Apple TV and Android TV, and also supports streaming via Apple AirPlay and Chromecast. The range of programmes includes more than 200 TV channels (in Germany, more than 100). These include public, private and international channels. The 7-day replay function and the video-on-demand service also enable the time-independent retrieval of selected programmes. Zattoo users can choose models that are financed either by advertising or by subscriptions.
In its B2B operations, Zattoo has been offering a fully hosted and managed OTT and IPTV service for network operators and media companies since 2012. This includes the complete ingest chain from live TV and Video on Demand content, including encoding, transcoding, multi-DRM and storage through to playout and front-end applications. The company focuses on providing a White Label Product with market-proven applications for all the relevant devices – from set-top boxes and streaming devices like Apple TV or Amazon Fire TV to mobile platforms such as iOS, Android or Windows 10.
Zattoo operates the entire service for its B2B clients as an end-to-end solution[buzzword] and guarantees the operation of the entire TV platform including White Label applications for all devices. Zattoo is constantly developing the service and the applications further with continuous updates and innovations.
The TV as a Service approach enables network operators and media companies to launch a TV service under their own brand without having to invest in their own hardware or software. Another benefit of this approach is how quickly the projects can be carried out. There are now more than 20 B2B customers from Europe and the USA on the Zattoo platform, and these in turn have several million end customers.
Zattoo was created to stream the 2006 FIFA World Cup in Germany. On 20 April 2007, Zattoo launched in Denmark with ten channels and started piloting in the United Kingdom. On 4 October 2007, Zattoo reached one million registered users in Europe.
Zattoo has been available in Spain since 10 June 2007. On 5 August 2008, Zattoo asked its Spanish users for a €2.40 charge by SMS in order to continue with the service during August and September. In March 2009, Zattoo removed its services from Belgium in an attempt to keep its costs down. Despite this removal of services from Belgium, Zattoo would return if it found a suitable marketing partner. Zattoo is now available in Germany, Spain, Denmark and Switzerland.
In May 2009, lawyers for Universal and Warner Bros. instigated legal proceedings against Zattoo claiming that the Swiss website - which rebroadcasts a number of television stations live online - is adding advertising to films that are shown on German TV via its online service.
On 23 April 2010, Zattoo dropped all the BBC channels from their UK channel list, after ongoing pressure from the BBC to remove them. On 15 June 2010, Zattoo dropped ITV1, Channel 4 and Five from their UK channel list, leaving none of the main UK channels; however, ITV's Northern Ireland (UTV) franchise remain.
Since June 2015, Zattoo Germany integrates an on-demand TV function, which enables viewers to watch a broadcast up to seven days after their TV broadcast in full length. The UEFA Euro 2016 provided Zattoo with a new user record: a total of 1.8 million viewers watched the games on the OTT platform, more than 800,000 of them in Germany. A quarter of the TV consumption during the Euro 2016 through Zattoo took place using TV sets connected to the internet, further narrowing the gap to smartphone/tablet usage (35%) and web usage (40%).
In December 2016, Zattoo reached two million monthly active users. Zattoo has introduced restart functionality for 50 TV channels for its German customers including channels offered by RTL and ProSiebenSat.1. If a user missed the beginning of a show, they can start the show from the beginning. Zattoo also offers a recording function which enables users to record up to 30 TV shows.
Since January 2018 Zattoo enables cross-border TV streaming for German users within the EU. This means that they can watch German TV programmes while staying temporarily abroad in another EU country. A registration with Zattoo and a PREMIUM account (paid subscription) are required. 
Zattoo is also an expert for Programmatic TV. The company offers dynamic advertising insertion (DAI) to advertisers. With DAI it is possible to embed video commercials in the TV live stream.
To continue its expansion in the Asia-Pacific region Zattoo has opened a new office in Singapore at the beginning of the year. 
Chip.de tested German TV streaming service in the following four categories in June 2017: number of channels, picture quality, type of end-user use and range of functions / service. According to Chip.de Zattoo, the best price performance with additional functions such as the break and restart functions is offered.
As of 28 January 2019, Zattoo takes over the end customer business of Magine TV Germany, which is discontinuing its TV streaming service in Germany. 150,000 affected users will receive a welcome offer from Zattoo to continue watching HD TV on all Internet-enabled devices and to use time-shift TV features.
The service is currently available in Switzerland and Germany. B2C Activities in other European Countries were ceased. Zattoo will grow internationally with its partners in the B2B business.
On 19 December 2009, the Audiovisual Media Services Directive regarding watching TV online from other EU countries came into force. This does not affect Zattoo or other P2PTV providers at all, since the directive only changes the jurisdiction where a country does not allow the reception of a foreign TV channel due to different laws. But the reason why P2PTV channels are not available all over the EU is not that the country of the viewer would not allow it, but that the TV channel itself cannot allow it due to licensing restrictions of the TV programs.
