For the first years of its existence, YouTube offered only one, low-definition resolution of 320x240 at 30fps or less, later extending first to widescreen 426×240, then to gradually higher resolutions; once the video service had become well established and had been acquired by Google, it had access to Google’s radically improved storage space and transmission bandwidth, and could rely on a good proportion of its users having high-speed internet connections. In 2013, YouTube extended further into the LDTV realm by adding an even lower 256×144p resolution with a halved framerate giving an overall effect reminiscent of early online video streaming attempts using RealVideo or similar services, where 160×120 at single-figure framerates was deemed acceptable to cater to those whose network connections could not even sufficiently deliver 240p content.
