London 2012: Naming rights for sale for Olympic venues
Long-term naming rights and sponsorship deals are being sought for London 2012 Olympic Park venues.
Rights for the Olympic Stadium, Multi-Use Arena and Aquatics Centre have been made available.
Parties have until 2 March to formally register their interest, with a final decision to be made in May.
"We are looking for sponsors who share our vision to create a Park that promotes healthy living," said Legacy Company chief executive Andrew Altman.
The venues and Park will begin to re-open in 2013 after they have been converted into their use beyond this summer's events.
The drive to create a lasting legacy for the Games infrastructure will see the Multi-Use Arena - also known as the Copper Box - host cultural as well as sporting events, while the Aquatics Centre will continue to boast two 50m swimming pools.
West Ham are believed to be one of 16 parties to have expressed an interest in moving to the Olympic Stadium, which will retain the athletics track, after the Games.
The government opened a tender process on 20 December and bidders have until 23 March to submit full proposals.
