ESPN2 debuted on October 1, 1993, as a sister station of ESPN. Nicknamed "the deuce," ESPN2 was to be branded as a network for a younger generation of sports fans featuring edgier graphics as well as extreme sports like motocross, snowboarding, and BMX racing. This mandate was phased out by 2001, as the channel increasingly served as a second outlet for ESPN's mainstream sports coverage.

Sports events presented on ESPN2 tend to be alternative sports such as poker, billiards, lumberjacking, extreme sports and, more recently, drum and bugle corps. However, in recent years ESPN2 has broadcast increasingly more mainstream sporting events, including Major League Baseball games, the East-West Shrine Game, much of the 2006 World Baseball Classic, many Major League Soccer and NCAA Basketball games, the WNBA, the Arena Football League, NASCAR Nationwide Series races on Saturday afternoons, and the Grand Slam Tennis tournaments the Australian Open, French Open, Wimbledon, and (beginning in 2009) US Open.
ESPN2's former flagship show, the morning sports/entertainment program Cold Pizza, achieved minimal success and saw several format and host changes. In January 2006, it was supplanted by the TV simulcast of ESPN Radio's Mike and Mike in the Morning (which moved from ESPNEWS) and moved to a later time slot (10a-12n EST). In May 2007, Cold Pizza moved from New York City to the ESPN headquarters in Bristol, and was renamed ESPN First Take. In February 2007, NASCAR Now made its debut on ESPN2. To cover NASCAR news, updates, and stats. Plus, NASCAR Now has special 1-hour called a "roundtable" editions on Monday's.
In 2003, ESPN2 began broadcasting Major League Lacrosse games. In March 2007, both agreed on a contract that will run until the 2016 season. 
Quite Frankly with Stephen A. Smith, a program that featured interviews with popular sports figures, had averaged extremely low ratings, and had also faced several time slot changes, until it was finally canceled in January 2007.
Every Saturday morning on ESPN2 is "Bass Saturday" where Bass Fishing programs are shown.
On February 1, 2007, the sports-media blog Deadspin reported that ESPN2 branding will be soon dropped entirely, in favor of ESPN, for the channel's in-game graphics, similar to the current ESPN branding on ABC sports broadcasts. The ESPN2 brand would be retained only for identification between the two channels, such as in the BottomLine. This change took place in full effect on February 12, 2007, as all on-air graphics (scorebox, transitional, mic flags, etc.) began using the ESPN logo rather than the ESPN2 logo. Another, more subtle change was made to the BottomLine, which is now red like the version of the BottomLine used on the main network; as expected, the ESPN2 logo remained on the BottomLine and ESPN2HD pillarboxes to further distinguish ESPN and ESPN2. ESPN2 got a new look in 2001.
ESPN2HD is a cable television network owned by Disney that broadcasts 24/7. It is a high definition simulcast of programs from ESPN2 including live sports and specials.
ESPN2HD has been adding more high definition programing with the addition of NASCAR Now, ESPN First Take, and Mike and Mike in the Morning. All three shows are broadcast from the ESPN Digital Center in Bristol, Connecticut. There are at least 8 and a 1/2 hours per day of High Definition programing plus whatever live sporting events are shown.
For the 2006 FIFA World Cup, most games were shown on ESPN2 and ESPN2HD, marking a major milestone for the network. Availability of the network is growing, with more cable providers (Cablevision, Comcast, Cox, Time Warner Cable, and others) and satellite providers (Dish Network and DirecTV) carrying the HD version.
Just like ESPNHD, ESPN2HD uses stylized pillarboxing, meaning that when the program being shown is only available in 4:3 standard definition (and not 16:9 high definition), the ESPN2HD logo is used to fill in the blank space on the sides.
ESPN2 also simulcasts some ESPNEWS programming, often during local blackouts, and for a while provided a Sunday simulcast of ESPN Deportes' SportsCenter.
ESPN2 also often carries SportsCenter on days where the regular ESPN broadcast is overrun by a longer than expected sporting event. Several times ESPN has carried a special entitled "This is Sportscenter" which was a live behind the scenes look into the making of Sportscenter. The show aired for 2 hours, including the lead up to the broadcast at 11pm. This showed how segments were planned, stories written, and guests readied for interview. The finished sportscenter would air live on ESPN2 while the behind the scenes feed would air on ESPN. This special has aired only twice, the last being in 2004.
Both ESPN and ESPN2 carried ABC News coverage of the September 11, 2001 attacks.
ESPN2 also aired the men's basketball SEC Championship Game in 2008 to most of the nation, since a storm destroyed the initial site of the tournament, causing the schedule to be rearranged in conflict with CBS's coverage of the Big Ten Championship Game. The game was produced by CBS. In SEC territory, the Big Ten game appeared on ESPN2.
