The race, the biggest in the UK racing calendar, was part of a package acquired by BBC Sport which also covers all other races in the three-day meeting at Aintree; 13 in total.
Said Ben Gallop, editor of BBC Sport Interactive: "We are about to embark on a major relaunch of our audio-video service, as we approach a huge summer of sport.
"And the National is the latest in a series of big events, which will culminate in the BBC's first ever broadband coverage of the Olympics."
The BBC has signed a deal to allow it to cover the Grand National horse race live on the internet.
