Comscore is an American media measurement and analytics company providing marketing data and analytics to enterprises; media and advertising agencies; and publishers.
Comscore was founded in July 1999 in Reston, Virginia. The company was co-founded by Gian Fulgoni, who was for many years the CEO of market research company Information Resources, Inc. (IRI) and Magid Abraham, who was also an ex-IRI employee and had served as president of IRI in the mid-1990s.
On March 30, 2007, Comscore made an initial public offering of shares on the Nasdaq, using the symbol "SCOR".
Co-founder Gian Fulgoni, who had been serving as chairman emeritus since 2014, replaced Serge Matta as chief executive officer on August 10, 2016. On September 2, 2016, Comscore received a letter from NASDAQ that it was in danger of being delisted from the exchange on September 12 unless Comscore filed its 2015 annual report (form 10-K) and reports for the first two quarters of 2016. On Feb 6, 2017, Comscore announced they would not meet the NASDAQ-imposed deadline to "complete its financial restatement and regain compliance with Nasdaq's listing requirements." Because of this missed deadline, "Comscore's common stock may be suspended from trading and delisted from Nasdaq." If Comscore is delisted from NASDAQ and their trading is suspended, they advise they intend to "be quoted on the OTC Markets." In November 2017, According to the reports, Gian Fulgoni co-founder and CEO retired.
On April 23, 2018, it was announced that Bryan Wiener was appointed as the company's chief executive officer, effective May 30. Wiener had previously served as chairman of 360i, a 1,000-person advertising agency known for its ability to help brands capitalize on change through innovation and a data-driven approach to marketing.
Comscore acquired Media Metrix in a deal announced in June 2002. Earlier, the Federal Trade Commission announced it would block a bid by NetRatings to acquire Media Metrix.
Media Metrix originated as PC Meter, a business unit of market research company NPD Group, and began publishing statistics in January 1996. In July 1997, it changed its name to Media Metrix. In October 1998, Media Metrix merged with a rival, Relevant Knowledge. The company went public as NASDAQ:MMXI in May 1999, reaching a market cap of $135 million on its first day of trading. In June 2000, the company acquired Jupiter Communications for $414 million in stock and changed its name to Jupiter Media Metrix. In the aftermath of the dot-com bubble collapse and associated downturn in internet marketing spending, Jupiter sold the Media Metrix service to rival Comscore for $1.5 million in June 2002.
In May 2008, Comscore announced its acquisition of M:Metrics, a company that measured mobile content consumption. The transaction involved a cash payment of $44.3 million and the issue of approximately 50,000 options to purchase shares of Comscore common stock to some M:Metrics unvested option holders.
In February 2010, Comscore announced an agreement to purchase the ARSgroup, headquartered in Evansville, Indiana.
In September 2015, Comscore and Rentrak announced a merger of the two companies. The move was meant to combine Comscore's digital media measurement capabilities with the TV measurement capabilities of Rentrak to create a cross-platform media measurement firm, perhaps capable of challenging Nielsen N.V. in the media measurement space. Under terms of the agreement, Comscore agreed to acquire Rentrak in an all-stock deal valued at about $732 million, with Rentrak shareholders receiving 1.15 shares of Comscore per owned share of Rentrak.
Comscore maintains a group of users who have monitoring software (with brands including PermissionResearch, OpinionSquare and VoiceFive Networks) installed on their computers. In exchange for joining the Comscore research panels, users are presented with various benefits, including computer security software, Internet data storage, virus scanning and chances to win cash or prizes.
Comscore estimates that two million users are part of the monitoring program. However, self-selected populations, no matter how large, may not be representative of the population as a whole. To obtain the most accurate data, Comscore adjusts the statistics using weights to make sure that each population segment is adequately represented. To calculate these weights, Comscore regularly recruits panelists using random digit dialing and other offline recruiting methods to accurately determine how many users are online, aggregated by geography, income, and age. Correcting the Comscore data requires having accurate demographics about the larger pool of users. However, some Comscore users are recruited without being asked to give demographic information and, in other cases, users may not be truthful about their demographics. To ensure the accuracy of the data, Comscore verifies its users' demographics during the course of measuring statistical data.
In May 2009, Comscore introduced Unified Digital Measurement (UDM), a digital audience measurement tool that blended panel and census-based measurement approaches. The methodology calculates audience reach without being affected by cookie deletion and cookie blocking/rejection.
Comscore debuted Campaign Essentials in 2010 to measure how digital campaigns are reaching their audiences. In March 2012, Comscore launched validated Campaign Essentials (vCE), which introduced the notion of “validated” impressions. In January 2013, Comscore announced that it had evaluated 4,000 campaigns for clients covering more than 75 advertising agencies.
In 2006, Ben Edelman, a Harvard researcher, alleged that there were cases where Comscore software had been installed on users' computers without their knowledge. Comscore admitted that it was in discussion with a spyware firm called DollarRevenue but said that no contract was ever signed, and that once it realized DollarRevenue was distributing Comscore's software, months later, it took steps to prevent the DollarRevenue-distributed software from sending data to Comscore. Stanford IT notes that the monitoring software has been bundled with file sharing program iMesh without users being aware of it, although Comscore's relationship with iMesh was short-lived and occurred several years ago.
In the past, the software forwarded users' internet traffic through Comscore proxy servers, provoking criticism about speed performance. As a result, several universities and banks took steps to block the proxy servers. In response to these concerns, Comscore no longer uses this technology. 
In June 2010, a warning about Mac Spyware being launched from free applications like screensavers, from security company Intego was reported in the media and implicated VoiceFive, Inc. as the source of certain alleged spyware software.
Additionally, noted blogger and angel investor Jason Calacanis claimed that Comscore was running an 'extorting ring' by vastly undercounting publisher traffic numbers and forcing them to pay fees for direct measurement via a tracking pixel. Comscore responded to these allegations by offering their direct measurement tracking pixel to long-tail web publishers for free.
