[4] The club's minority shareholders include its current head coach, Cesc Fàbregas, and football legend Thierry Henry.

[13][14] In the first years after its foundation, Como played friendly matches and local tournaments, competing against teams from Milan and Switzerland.

[14] On 1 October 1911, the club took part in the inauguration of the Campo via dei Mille by playing in a friendly match, defeating Bellinzona 3–1.

Como was therefore registered in the Lombardy Promozione group, and played its first match on 17 November 1912 with a 5–0 win over Brescia at Campo via dei Mille.

[15][16] In 1927, Como merged with Esperia and was renamed Associazione Calcio Comense, which won the Coppa Volta in the same year, eliminating Inter 3–0 in the semi-final and beating Genoa 1–0 in the final.

The following year, in their first experience of Serie B, the Como side comfortably avoided relegation, finishing in ninth place with a young Marco Romano as their top scorer.

[14] World War II dramatically affected the entire Italian football movement, but Como managed to bounce back.

[17] In the early 1960s, Como's campaign in the second division had to be stopped following the "Bessi case", a case that began at the start of the 1962–63 Serie B season when the club fielded defender Paolo Bessi for five matches, who had just been bought from Tau Altopascio without knowing that the player was not yet finished serving the disqualification sentence imposed on him by the Tuscany Regional Committee of the Lega Nazionale Dilettanti.

[14] After saving themselves on the pitch, Como were punished with five default defeats which saw them relegated to Serie C. In their first year of relegation to Serie C, the club finished third in Group A after a squad completely rejuvenated and renewed by coach Vinicio Viani, with Bruno Ballarini and Giovanni Invernizzi remaining the club's mainstays.

After four years in Serie C, promotion finally came in the 1967–68 season when the team finished top of Group A under coach Franco Viviani and still led by historic captain Bruno Ballarini, Como's record appearance holder in the competitive matches.

[14] In the 1973–74 season, following the arrival of Giuseppe Marchioro as coach, Como again fought for promotion with a solid defense of Antonio Rigamonti and Vito Callioni, but the team could only finish in a fourth place.

[14] Como managed another promotion to the top flight in 1984, with a five-year stint in Serie A proving the club's most successful period.

The strikeforce of Dan Corneliusson and Stefano Borgonovo oversaw a 9th-place finish in 1986, which was repeated the following year with far fewer goals scored.

Promotion to Serie B in 2001 was marred by an appallingly violent incident in a game against Modena, resulting in captain Massimiliano Ferrigno being handed a three-year ban.

[18] No investor was successful to take over the club as the bid from Enrico Preziosi was denied, and thus the company Calcio Como S.p.A. was liquidated.

[7] In this season, the club also won the Coppa Italia Serie D after beating Colligiana with an aggregate score of 3–1 in the two-legged final.

[8][24][25] In 2019, the club was acquired by Indonesian company Djarum Group, led by Robert Budi Hartono and Michael Bambang Hartono, after the club won the Girone B of 2018–19 Serie D. Como returned to professional football that year under the ownership of the brothers, who as of 2022, earns €4 million per hour according to Forbes.

After the exemption granted to him expired, on 20 December Como appointed Welshman Osian Roberts as head coach, with Fàbregas being demoted as his assistant.

Promotion was secured on the final matchday of the season on 10 May 2024, against Cosenza which ended 1–1, making the club finish as runners-up above Venezia with a three-point lead and just below Parma, the Serie B champion.

[37] The element that has characterized almost all the badges that Como has used over the decades is the city's coat of arms in red with a silver cross in the center.

Since the early 1950s, a new badge was introduced, a blue modern French shield with the club name – Calcio Como in canary letters, and the city's coat of arms emblazoned in the top left corner.

[39] In 1991, a change to the badge occurred when a white ancile was introduced, containing the city's coat of arms in the center flanked by blue waves.

The design is presented monochromatically in blue or white depending on the surface of the application, while the red component is completely absent.

In the third millennium, the club colours tended to decline to royal blue,[41] which also gave rise to the nickname Biancoblù.

In 1926, when the club merged with Esperia as Associazione Calcio Comense, garnet red was chosen as a sporadic condiment on the shirts.

[44] Although the club secured promotion to Serie A in May 2024, it remains unclear whether they will play their home games at Sinigaglia during the 2024–25 season, as the stadium currently does not meet the minimum capacity requirements set by the league.

Other rivalries are with the supporters of Modena, Livorno, Atalanta, Venezia, Palermo, Cremonese, Brescia, Verona, Sampdoria, Ternana, Piacenza and others.
