Investec, the international specialist bank and asset manager, became the new title sponsor of Test match cricket for the next 10 years at the start of 2012.
The sponsorship, which runs until 2021, is the longest sponsorship agreement secured in the ECB's history.
It begins in summer 2012 when England take on West Indies and South Africa. This will be followed by three home Ashes series against Australia in 2013, 2015 and 2019, and major tours by India in 2014 and 2018, Pakistan in 2016 and South Africa in 2017.
ECB chief executive David Collier said: "This is excellent news for all supporters of Test cricket and a further boost for our five-day game following the England team's recent achievement in becoming the world's number one ranked Test side.
"Investec are an established brand with extensive experience in the sports sponsorship field and we are delighted that they have made such a significant, long-term commitment to promoting Test cricket in this country.
"The extent of their investment reflects the fact that our five-day game continues to command very significant audiences - both at home where we achieved record attendances for international cricket in 2011 and abroad where the England team is gaining increased exposure in markets such as Asia, South Africa and Australia.
"ECB has an excellent track record in developing and sustaining business partnerships across professional and recreational cricket and we look forward to working closely with everyone at Investec over the coming decade."
As part of the agreement, Investec will receive a comprehensive range of sponsorship and advertising rights which will include ticketing, hospitality and access to England players.
The London and Johannesburg-based firm becomes only the third company ever to sponsor Test match cricket in this country. Raymond van Niekerk, global marketing director of Investec, said: "Investec is delighted to announce this landmark 10-year sponsorship of Test match cricket in England. The five-day game requires intelligence, teamwork, adaptability and a strong competitive spirit; attributes that are closely aligned to Investec's business values.
"We are excited to begin our sponsorship with England as the world number one team in the Test rankings, following their impressive defeat of India in the summer. Investec has an established track record of enhancing the sports events it is associated with and we look forward to working with the ECB over the coming years."
