When Bitcoin started, every block rewarded 50 BTC to the first miner to 'solve' the block. Bitcoin is programmed to reduce this amount every 210,000 blocks, halving the amounts roughly every 4 years.

The First Halving
Until November 28th 2012, every miner was rewarded with 50 BTC for every block that was mined. The first 210,000 blocks were mined by people like Satoshi Nakamoto himself, Hal Finney and early adopters. A huge amount of those Bitcoins is lost in hard drives. A lot of them sold. Some others still hodl.
The first halving saw miners reducing their reward to 25 BTC per block. Price wise, Bitcoin started it's first week with positive market action at $12.32, followed by four weeks of small downward movement, reaching a lower point of $12.70.

Afterwards, Bitcoin saw a brutal bull market in which it traded for $1163 in November 2013. This would have given a return of 9000% if someone bought BTC on halving day up to the top of the bull market.
