Question: Which brand sponsored the competition that Reggina Calcio was re-promoted to?
Context: Serie A (] ), also called Serie A TIM due to sponsorship by TIM, is a professional league competition for football clubs located at the top of the Italian football league system and the winner is awarded the Coppa Campioni d'Italia.  It has been operating for over eighty years since the 1929–30 season.  It had been organized by Lega Calcio until 2010, when the Lega Serie A was created for the 2010–11 season.  Serie A is regarded as one of the best football leagues in the world and it is often depicted as the most tactical national league.  Serie A is the world's second-strongest national league according to IFFHS and has produced the highest number of European Cup finalists: Italian clubs have reached the final of the competition on a record 27 different occasions, winning the title 12 times.  Serie A is ranked third among European leagues according to UEFA's league coefficient, behind La Liga, the Premier League and ahead of the Bundesliga and the Ligue 1, which is based on the performance of Italian clubs in the Champions League and the Europa League during the last five years.  Serie A led the UEFA ranking from 1986 to 1988 and from 1990 to 1999. Reggina Calcio did renew its Serie A contract on the second consecutive occasion, ensuring the longest stay of the Calabrian club in the top division of Italian football.  With returning coach Franco Colomba not being successful in his third stay at the club, Giancarlo Camolese guided the side to 13th place in the league.  With only 29 goals scored, Reggina relied heavily on its defence for the survival, and Martin Jiránek plus defensive midfielder Davide Baiocco strengthened their reputations.  After the season, Baiocco returned to Juventus, who in turn loaned him out to Reggina's arch-rivals Messina, newcomers for the 2004–05 season, setting up the first Messina strait derby in the highest division ever. Reggina Calcio was re-promoted to Serie A, following a reliable performance in the 2001-02 Serie B, following its narrow relegation from the top tier.  With Gianluca Savoldi and Davide Dionigi being supported by playmaker Francesco Cozza, Reggina had one of the most effective offenses in the league, and the third place was well clear of fifth-placed Napoli, the club which signed Reggina's successful coach Franco Colomba following the season's end. Erol Bekir, formerly known as Erol Bekirovski, (born 25 January 1974) is a Turkish-Swedish football manager and former player of Turkish origin with roots from Macedonia.  He started out playing for his hometown club Malmö FF in Sweden but spent most of his career playing abroad for clubs like BSC Young Boys, FC Lugano, Reggina Calcio, FC Thun and SV Waldhof Mannheim.  Upon returning to Sweden he signed with lower division Malmö club IF Limhamn Bunkeflo where he also became player manager before retiring as a player and focusing only on the manager part at the end of 2009.  In August 2012, IF Limhamn Bunkeflo and Bekir went their separate ways after the club announced that they could not match Bekirs level of ambition. Reggina Calcio were relegated following losing three key players in the summer of 2000.  Despite goalkeeper Massimo Taibi being in full form following his Manchester United debacle, Reggina had serious goal scoring problems without departed striker Mohamed Kallon.  With Davide Dionigi arriving from Sampdoria mid-season, Reggina solved that problem, and Dionigi's six goals led to a "spareggio" for the Serie A stay, a double-header Reggina lost.  Coach Franco Colomba was not blamed for the relegation, and was given the all-clear to stay for a further season, with Reggina one of the favourites to bounce back to the top domestic division. Reggina Calcio just renewed its Serie A contract, thanks to a late surge in the league competition and a successful "spareggio" against Atalanta.  Reggina drew 0-0 at home, and then turned around a deficit to win 2-1 away from home, with Francesco Cozza and Emiliano Bonazzoli being the match-winners.  The player who got the most headlines during the season was Japanese playmaker Shunsuke Nakamura, who scored seven goals and created several others.  He also helped Reggina to get onto the Asian market, so the signing was largely hailed as a genial manoeuvre by president Pasquale Foti. Reggina Calcio was thought to be certain to be relegated in the 2006-07 season, since it had been deducted eleven points for its involvement in Calciopoli.  At no stage had Reggina renewed its contract with more than a point or two, and therefore its 51 points from 38 league matches sent echoes over the entire Italian football society.  The Serie A stay was extended thanks to the successful striking force of Rolando Bianchi and Nicola Amoruso, scoring an unprecedented 35 goals between them, a figure any top club would have been delighted of.  Bianchi headed for Manchester City in the summer, and successful coach Walter Mazzarri found a new berth at Sampdoria, leaving Reggina with its Serie A status intact, but back on square one again. Reggina Calcio finally dropped out of Serie A, following seven years of balancing around the drop zone.  Following its previous six years, the club had stayed in Serie A by less than three points on alla occasions.  In 2008–09, Reggina dropped off the pace mid-season and was nowhere near survival. Reggina Calcio took major steps in establishing itself in Serie A under new coach Walter Mazzarri.  The relegation battle was the tightest ever, but Reggina's points average was its highest in the top division yet, resulting in a surprising 13th place.  That also meant it lost several key players, with Shunsuke Nakamura, Martin Jiránek and Emiliano Bonazzoli being hard to replace. Reggina Calcio extended its stay in Serie A by a further season, despite being charged with involvement in Calciopoli at the end of the term.  Reggina was allowed to retain its Serie A status, but was demoted eleven points out of its 2006-07 campaign, leading to the general consensus that its time in the top-flight division was running out, given that it had only sealed its Serie A stays by the shallowest of margins before.
