The number has gone up quite a bit since then since the hashrate is rapidly growing.
At the moment, it's $80,000,000, though it will step down again when I can fairly make the claim $3/gh 28nm parts, instead of $8000 for 400GH/s bitfury parts. ($3/gh would be $12m at current hashrate, though once those parts are actually available the hashrate will go up some large amount).
To elaborate on Maaku's comment. Bitcoin is foremost an autonomous zero trust system, all full nodes validate everything. A majority of mining ruins the security assumptions, but it still doesn't give the majority completely free reign over the system. Dishonestly using your majority hashpower would likely just make the resulting coins worthless.
