RealPlayer

[7] RealPlayer is also available for other operating systems; Linux, Unix, Palm OS, Windows Mobile, and Symbian versions have been released.

RealPlayer was initially accessed by many users as a plugin to watch streaming video or listen to streaming audio (for example, most of the BBC's websites formerly employed the plugin);[10] but in the early 21st century, Adobe Flash and subsequently HTML video became preferred options for this purpose.

The available visualizations from the RealNetworks site are: FrequencywurX, FyrewurX, FlamewurX, X Factor, Spectral View, FluxWave, Puddle, Paint Drops, Polka Dots, SticksterZ 1.0, Circle, TomTom On the Road, Real Logo, and Hubble Bubble.

[46] There are some more visualization plug-ins like SurrealFX by RealNetworks, G-Force and WhiteCap by SoundSpectrum and SticksterZ 1.1[47] by Eric Metois.

RealPlayer SP includes audio CD burning capabilities, DVR-style playback buffering, multimedia search, Internet radio, a jukebox-style file library, an embedded web browser (using Microsoft Internet Explorer), and the ability to convert and transfer media to a wide range of devices.

[50] The last stable release as of July 2010[update] included Real's Helix playback engine for RealAudio and RealVideo, a 10-band equalizer and video adjustment controls, and a full-screen, resizable "theater mode" for video playback, as well as many features found in its Windows counterpart.

RealJukebox was a media player that allowed users to play and manage their digital music on hard drives, CDs and online.

[58] In 1999 security researcher Richard M. Smith dissected some of RealJukebox's network traffic and discovered that it was sending a unique identifier with information about the music titles to which its users were listening.

[62] PC World magazine named RealPlayer (1999 Version) as number 2 in its 2006 list "The 25 Worst Tech Products of All Time", writing that RealPlayer "had a disturbing way of making itself a little too much at home on your PC installing itself as the default media player, taking liberties with your Windows Registry, popping up annoying 'messages' that were really just advertisements, and so on.

[63] US-CERT has issued multiple security advisories reporting defects which allowed remote sites to use RealPlayer to execute attack code.

[64][65] Real Alternative is a codec which allows RealMedia files to be played without the installation of the RealPlayer software.

[67][68] The case was reopened in 2013, when RealNetworks claimed to possess further proof showing that Edskes was involved in uploading Real Alternative.
