The band toured nationally and shared stages with the likes of The Juliana Theory, Anberlin, Finch, Further Seems Forever, and Seether as well as performing successfully on the Warped Tour and Cornerstone Festival. When the band's debut record, Lost For Words came out on Seattle indie, Rocketstar Records, and quickly approached the 5000 sales mark, the industry at large began taking notice. When the band recorded a new 5-song demo with Aaron Sprinkle, this industry interest turned into serious courting by several major labels. After putting a professional management team in place to help determine the band's course of action, the band made the decision to release the Black Lines To Battlefields EP, produced by Aaron Sprinkle on The Militia Group who had been a long-time supporter of the band.

Acceptance later signed to the larger Columbia Records and released their debut album Phantoms in 2005, again produced by Aaron Sprinkle. The album was one of many included in the Sony rootkit controversy due to its inclusion of the Extended Copy Protection software.

In early 2006 they were declared "greatest rock band of the urban era" by MTV. Acceptance broke up in the summer of 2006. Former guitarist Christian McAlhaney posted the following message on their site:

You see, there comes a time in a band member’s life where he must choose between the abnormal life of a gypsy rock musician and the normal life of the common man. Jason, our beloved lead singer, has chosen the latter and decided to take on the yoke of the common man. HOWEVER, the rest of us do not share in this desire for normalcy and have decided to continue in our pursuit of rock stardom. You should all be expecting to hear a new kick ace rocking project from Nick, Kyle, and I, as well as a new project from Kaylan and a bunch of secret people that I can't talk about right now.

At the time of the band's breakup, they had already written and demoed songs for a new album. As a "going away" for fans, the band put the demo for "Not Afraid" up on their Myspace page for download.

Jordan Riley joined as frontman of the band until leaving to pursue a different musical career, leaving the band and continuing on with his own projects. Jordan is now a very successful Studio Musician, and solo artist carrying his band If We Were Lions to new levels.

Kaylan Cloyd has joined Ryan Van Wieringen and Bobby Darling of Gatsbys American Dream to form Search/Rescue. The band released their debut album, titled The Compound, in Japan in late 2007 with a US release in early 2008 on Eyeball Records.

Christian McAlhaney currently plays guitar in Anberlin.

Nick Radovanovic, Christian McAlhaney, and Kyle Flynn started a band called Thunder Thunder with Jerrod Bettis. Their current status is unknown due to McAlhaney's commitment with Anberlin.

Kyle Flynn currently resides in Los Angeles, CA and is working on a script with his brother Kevin Flynn for Warner Bros. Pictures. It has recently been announced that he will be touring with Anberlin. Jason Vena has retreated from the limelight, seemingly fulfilling his desire to lead a "normal" life. He's apparently currently working for his family's business in Mercer Island, Washington.

On November 24, 2007, Nick Radovanovic posted a bulletin on Acceptance's Myspace stating that he is currently working with two bands, A Modern Love Story and A Novel Form, both of which have albums coming out soon.

On May 30 Nick Radovanovic posted a remixed version of the song "So Contagious" on Acceptance's myspace page.

Drummer Jerrod Bettis (Faster Avenue, OneRepublic) has joined Search/Rescue with ex-Acceptance members Kaylan Cloyd, and Ryan Zweifelhofer.
