In athletics, races have to be timed accurately to hundredths (or even thousandths) of a second. A battery of electronic devices are installed in high-profile events (such as the Olympic Games) to ensure that accurate timings are given swiftly both to the spectators and to the officials. The photo finish has been used in the Olympics since as early as 1912, when the Stockholm Olympics used a camera system in the men's 1500 metres race. The 1948 Olympics saw the finish of the men's 100 metre race determined with the use of photo finish equipment provided by Swiss watchmaker Omega and the British Race Finish Recording Company.
