Apple are officially the world's most valuable company after seeing their market value pass the $600 billion (£379 billion) mark.
The technology giant saw shares hit a new high of $644 on Tuesday, which is an incredible jump given that they were only valued at $500 each back in February.
This is in stark contrast to 1997 where, on the brink of going under, their shares were worth just $3.19.
Rival Microsoft is worth $260bn and in 1999, at the peak of the dotcom boom, reached $619bn in market capitalisation.
Apple's success has been built on the back of their excellent products, with the iPhone and iPad taking the tablet market by storm.
