Introduced in June 2015, the DxO ONE from DxO Labs is a small camera that attaches to an iPhone or iPad using the Lightning connector port.
 The DxO ONE has a 1-inch format, 20.2 megapixel image sensor—the same one that is found in the Sony Cyber-shot DSC-RX100—as well as an f/1.8 maximum-aperture lens and high-speed shutter.
 The ONE uses the attached mobile device as an electronic viewfinder for the camera—which does not have its own viewfinder.
 European Imaging and Sound Association awarded the DxO ONE its prize for photo innovation for 2015-2016.
 DxO has also created a website where photographers can showcase images taken with the DxO ONE.

 It features a rotating cast of comedic sketch groups who perform in front of a live audience.
 The groups are introduced by a host comedian, originally Humphrey Ker, now Thom Tuck.
 The show is currently in its third season.

 Sketchorama aims to bring hidden gems and established live acts to the airwaves offering a truly distinctive and ambitious show."
A sampler is a type of compilation album generally offered at a reduced price to showcase a selection of artists signed to a particular record label.
 The format became popular in the late 1960s as record labels sought to promote artists whose works were primarily available in album rather than single format, and therefore had little opportunity to gain exposure through singles-dominated radio airplay.
 Most samplers showcased already-released material, so that as they sampled artists they also sampled the albums from which their tracks were drawn.
Showcase In A Suitcase is a reggae album comprising showcase (songs followed by dubs) format material produced by Prince Far I, and performed by Prince Far I, Ashanti Roy, The Wailing Souls, and Naggo Morris.

 The album reached number six in the UK Reggae Chart published by "Sounds" in December 1980.

 The album was released in CD format in 1995.
The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of 33 ⁄ rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification.
 Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry.
 Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums.
Opus Nocturne is the third studio album by Swedish black metal band Marduk.
 It was recorded and mixed at Hellspawn Studios in September 1994 and released that December by Osmose Productions.
 It was re-released in digipak format that included bonus rehearsal tracks on June 27, 2006.
 "Opus Nocturne" is the last Marduk album to feature Joakim Göthberg on vocals and Dan Swanö as mixer.
 "Opus Nocturne" was the first album to showcase Marduk's signature hyper-speed blast beat tempo, however it still contained much of the melody from "Those of the Unlight" while retaining this break-neck speed, instead of sheer brutality on albums like "Heaven Shall Burn... When We Are Gathered" and "Nightwing".

 Within a few years, the 12" album was the format offered to the record buying public, remaining so until the mid-1980s when the Compact Disc took the market by storm.

 However, "Hanggang Ngayon" was Gonzaga's first credit as a songwriter.
